Everything follows the law, and there is harmony in the world. "In the vast field of petroleum research where Jiang Guancheng is located, he has always adhered to the concept of" learning from nature ", whether it is the theory and technology of biomimetic drilling and completion fluids, the theory and technology of dual porosity of rock surfaces underground, the theory and technology of predicting, protecting, and evaluating reservoir damage throughout the life cycle of oil and gas wells, or the technology of temporary blockage of physical and chemical membranes... He and his research colleagues are committed to using interdisciplinary scientific tools to create a" Garden of Eden "for the modern petroleum industry. He firmly believed that in this magical Garden of Eden, everything in nature could complement each other. As long as he observed carefully and harmoniously utilized it, he could play a harmonious and beautiful oil music.

　　▲The cover character of Scientific Chinese: Jiang Guancheng

In the depths of the earth, oil and natural gas are like "black gold" and "blue flames", silent, but containing surging power. Since the industrial revolution, they are not only the "blood of industry", but also the inexhaustible driving force for the progress of human civilization. According to the latest forecast of the US Energy Information Administration, oil and natural gas will still occupy the first place in the world's energy consumption before 2050. For a long time in the future, oil and gas will still be the main energy source that cannot be replaced for economic and social development. With the development of the times, the global oil and gas consumption demand is increasing year by year, and China's oil and gas supply dependence on foreign countries has long been high. In 2023, China's external dependence on crude oil will reach 72.99 percent, far higher than the international oil security warning line, and its external dependence on natural gas will be 42.3 percent, seriously affecting China's energy security and there is an urgent need to enhance its oil and gas self-sufficiency. It is urgent to enter deep, deep water, unconventional and other complex oil and gas. Just as oil and natural gas as the blood of industrial society continuously inject power and vitality into the operation of the world, drilling and completion fluid has the same status and function in drilling engineering-it is called "drilling blood", which has very important functions such as carrying rock cuttings, balancing formation pressure, stabilizing borehole wall, protecting reservoir, transferring water power, lubricating and cooling drill bit. With the large-scale development of deep, deep water, unconventional and other complex oil and gas resources, drilling and completion fluids will face more and more challenges in the drilling process, such as insufficient temperature resistance of treatment agents, difficult to control the rheological properties of drilling and completion fluids, poor hole cleaning, easy to cause wellbore instability, downhole leakage and other drilling risks, and difficult to control reservoir damage, which will affect the production of oil and gas wells or the discovery of new oil and gas fields. The challenges faced by drilling fluids and completion fluids have become a worldwide technical problem, and have become a "stuck neck" technology that restricts the "safe, efficient, economical and environmentally friendly" drilling of complex oil and gas. In order to solve this worldwide technical problem, scholars at home and abroad have racked their brains and made many useful attempts. Among them, the achievements of Jiang Guancheng, Professor of Oil and Gas Well Engineering Department of Petroleum Engineering College of China University of Petroleum (Beijing) and his research partners are unique. For example, following the concept of "learning from nature", Jiang Guancheng set his sights on the depths of the ocean. He was inspired by the super adhesive ability of the mussel's foot silk protein. He skillfully transformed this feature into a bionic strong solid wall drilling and completion fluid, which showed amazing effects in inhibiting the dispersion of drill cuttings, stabilizing the well wall and carrying cuttings, and effectively solved the problems of well wall instability. Over the years, he has also achieved a series of highly innovative and outstanding results, including the first to establish a quantitative "prediction, diagnosis and protection" technology for the entire process of reservoir damage in oil and gas wells, which provides a strong foundation for the efficient development and sustainable utilization of oil and gas resources. Strong technical support; establish the theory of double porosity of downhole rock surface and develop a series of technologies, and obtain large-scale applications in ultra-deep and unconventional oil and gas wells. The achievements have been evaluated by peer experts in academic journals as "revolutionary technological progress since the 1970 s", "leading the development direction" and "reaching the international leading level as a whole". The achievements have been industrialized in China's major oil fields and 11 overseas countries, with benefits of more than 10 billion yuan. Walking into Jiang Guancheng's scientific research world, you will find that bionic drilling completion fluid technology is not only an innovation, it is a deep understanding and lofty tribute to the laws of nature. His research is like a "magician" splashing ink on the picture of nature, which is not only unconstrained, but also strictly follows the rhythm and rhythm of nature. And this is the unique magic weapon that he has invested in drilling and completion fluid, reservoir damage and protection, and oilfield chemistry research for many years.

　　The light of oil illuminates the way forward

　　Looking back at Jiang Guancheng's research journey, his connection with the petroleum profession was not only a result of his personality, but also a result of environmental shaping. In his personality, there is a resilience and patience that allows him to sit on the cold bench, which enables him to calmly delve into the ocean of scientific research and continuously deepen his understanding. Jiang Guancheng was born in a rural area, and the difficult life endowed him with the qualities of hard work and endurance. This quality became a valuable asset in his later scientific career, allowing him not only to calmly deal with tedious data and complex experiments in the laboratory, but also to maintain composure and composure when facing harsh environments and unknown challenges in oil exploration sites. When filling out his college application for the college entrance examination, Jiang Guancheng did not blindly follow the trend. Instead, based on his own interests and the advice of his homeroom teacher, he voluntarily chose Southwest Petroleum University (now Southwest Petroleum University). At that time, although he only had a partial understanding of the oil industry, the scene of the Geological Exploration Bureau drilling wells next to the school to collect geological data during high school had already planted the seeds of exploring the mysteries of oil in his heart. With excellent academic performance, Jiang Guancheng successfully entered Southwest Petroleum Institute in 1983. This university located in the land of Chuanzhong is renowned for its profound academic background and outstanding achievements in the field of petroleum engineering. As one of the cradles of China's petroleum industry, this place has nurtured countless professionals in the petroleum field. Tong Manli, Yang Shiyu, Luo Pingya, Sun Jinsheng, Hu Xingqi, Chen Dajun, Cao Zhenzheng, Lei Xianzhang, Ye Zhongbin, Duan Ming, Zou Changjun, Pu Wanfen... These names shine brightly, illuminating the sky of China's petroleum research. Under the influence of this university, Jiang Guancheng spent four precious years of his undergraduate studies. When Jiang Guancheng first entered the university, his major was oilfield chemistry, which was one of the earliest majors established by Southwest Petroleum Institute in China and had a profound background. In the first two years of enrollment, this major was renamed Applied Chemistry. This transformation means that his academic journey is no longer limited to the field of oilfield chemistry, but has moved towards a broader realm of applied chemistry. This provides a more comprehensive and in-depth chemical knowledge system for his future innovative research in the fields of drilling and completion fluids. He learned how to flexibly apply the basic principles of chemistry to solve complex engineering problems, and this ability played a crucial role in his later scientific research work.

　　The light of oil illuminates the path ahead, and the song of exploration echoes in the heart. Accompanied by the melodious singing of Southwest Petroleum Institute, bathed in the golden sunshine, Jiang Guancheng grows strong and healthy. During the summer of his junior year, he was selected to assist Professor Huang Linji in participating in a major scientific research project during the national "Seventh Five Year Plan" period due to his outstanding performance. In that hot summer, he went to Chengdu Coking Plant with several classmates to participate in project experiments and solve on-site problems. This was his first time truly stepping into the world of scientific research, facing many difficulties at the beginning of scientific research. Fortunately, he had good teachers and friends to accompany him. In that era of underdeveloped information, he often traveled with a few classmates to Sichuan Library by bus or bicycle to search for information. The library had more complete resources than school and was a treasure trove of knowledge for them. On site, they were fortunate to receive guidance from their masters. These experienced masters not only provide technical guidance, but also encourage them spiritually. The school's guidance teachers also accompany them, providing them with careful guidance and selfless help. At the scene, Jiang Guancheng also heard many stories about the outstanding representative of Southwest Petroleum Institute, Academician Luo Pingya. Academician Luo, with his diligent research and fearless demonstration, has become a role model in the hearts of young students. He fought alongside the workers in a difficult working environment, demonstrating a spirit of dedication and sacrifice. These stories not only inspired Jiang Guancheng's exploration enthusiasm in drilling and completion fluid research, but also strengthened his belief in dedicating himself to the field of petroleum. Jiang Guancheng's first scientific research practice was of great significance to him, not only laying the groundwork for his future graduation project, but also laying a solid foundation for his comprehensive understanding of reservoir protection technology.

　　In 1987, Jiang Guancheng, who graduated with a bachelor's degree, went to teach at the Dongying campus of China University of Petroleum (East China). He sat on the bench for ten years and stayed there for more than 20 years. From honing his experience in important projects at the end of the Seventh Five Year Plan period to making a name for himself in the Eighth Five Year Plan period, he has gained one innovative breakthrough after another by integrating into the wave of China's petroleum strategic planning and development.

　　A heart of inquiry, guiding exploration

　　The Bai 24 well in Zhongyuan Oilfield, as Jiang Guancheng's first well drilled on site after working, left a deep impression on him. This well is located in Baimiao area, Dongming County, Heze City, Shandong Province, and the logistics department of the drilling team responsible for drilling the well is located in Lankao County, Kaifeng City, Henan Province - the place where Jiao Yulu once struggled. Jiang Guancheng often traveled back and forth between the two places for a long time in order to successfully dig the well. He and his team faced the challenge of low-permeability gas reservoirs and embarked on research and exploration. After more than a year of on-site practice, he deeply realized the difference between textbook knowledge and on-site practice, and also learned how to apply research results to the field and solve practical problems. Unforgettable was the shock brought to him by the on-site master. Even adding water to the drilling fluid, which seemed insignificant, was actually full of experience, knowledge, and wisdom. It involved selecting water quality, controlling mineralization, and accurately grasping the timing and amount of addition. After being taught by the master, Jiang Guancheng felt a sense of enlightenment. These details determine the performance of drilling fluid and affect the success or failure of drilling. Learning to add water is equivalent to learning the experience of drilling fluid on-site knowledge, "said Jiang Guancheng, the master. At the Bai 24 well, Jiang Guancheng had the opportunity to be exposed to cutting-edge technologies in China at that time, such as the application of comprehensive logging instruments. These new technologies not only broadened his horizons, but also provided him with new ideas and methods for his future scientific research work. With the deepening of practice, Jiang Guancheng felt that he could never learn enough. With a constantly seeking heart, he continued to climb the ivory tower and pursued a master's degree at China University of Petroleum (Beijing). At the same time, he faced the test of the national "Eighth Five Year Plan" horizontal well project, which had significant implications for his scientific research life, with a more full attitude. The "Complete Technology for Drilling Horizontal Oil Wells" is a national science and technology research project during the "Eighth Five Year Plan" period. It was jointly developed by Shengli, Xinjiang, Daqing, Dagang Petroleum Management Bureau, and Exploration Bureau, as well as several universities and research institutions. As the technical leader, Jiang Guancheng was fortunate enough to participate in the entire process from indoor research to on-site application, to writing acceptance reports and project acceptance. This experience not only honed his abilities as a researcher, but also served as an important test of his sense of responsibility.

　　▲Jiang Guancheng's team held a training course for young talents in energy and environment

The successful development of oil horizontal well drilling technology marks a new era in the drilling industry, but this change is not easy. Compared with traditional vertical wells, the drilling of horizontal wells is more complicated, requiring the drill bit to extend horizontally along the reservoir precisely in the deep underground. In this process, the drilling and completion fluid has a large area and a long time to contact the reservoir, which not only requires higher requirements on the wellbore stability, lubricity, rheology, leakage prevention and plugging ability of the drilling and completion fluid, but also requires more strict requirements on the ability to protect the reservoir, and measures must be taken to avoid damaging the permeability of the reservoir. These factors together constitute the difficulties of horizontal well drilling and completion fluid technology. To this day, Jiang Guancheng still clearly remembers the five major technical problems they faced: borehole wall stability, borehole cleaning, lubrication and anti-card problems, reservoir damage and leakage. These problems already exist in straight wells, but they are more severe in horizontal wells. Faced with the technical blockade, there is no ready-made experience to follow, they must independently develop special drilling and completion fluids suitable for horizontal wells. Through technical research, they have overcome one problem after another, and successfully drilled the first domestic horizontal wells with "long, medium, and short" curvature radii-the female MH-1 well, the official H-1 well and the official H-2 well, which are still clearly engraved in Jiang Guancheng's memory. The drilling of these wells marks a solid step forward in horizontal well drilling technology in China. As the main researcher, Jiang Guancheng promoted the project to form a complete set of horizontal well drilling and completion fluid technology through theoretical research, indoor test and actual construction on site, and achieved a number of innovative results. After expert appraisal, the results generally reached the international advanced level, and finally won the first prize of the 1997 National Science and Technology Progress Award. At the same time, he also felt the solid knowledge and perseverance of his predecessors. Difficulties and hardships Yu Yu cheng, everyone saw flowers and applause, only Jiang guancheng and his companions know that the results are not easy to get, in Dagang oilfield horizontal well field test days, living conditions are extremely difficult, even in the diet can eat flies, such memories so far let Jiang guancheng unforgettable. But it is such an environment, temper his will and perseverance. During the country's "Eighth Five-Year Plan" period, there is one more thing that is of vital importance to Jiang Guancheng. Trusted by his mentor, he undertook a project task to promote reservoir protection technology across the country, and shouldered the important task of imparting reservoir protection knowledge to petroleum workers at different levels. In order to better teach the course, he did not stop at the appearance of technology, but went deep into the oil field to conduct detailed research. His footprints are all over the major oil fields, from Jiangsu Oilfield to Dagang Oilfield. Every investigation gives him a deeper understanding of reservoir damage. In-depth investigation and rigorous lesson preparation, Jiang Guancheng discovered the shortcomings of the internationally used particle inlay protection technology-the principle is to use solid particles with a particle size equal to 1/2~2/3 of the average pore size of the reservoir to block the pore throat and prevent fluid intrusion. Because it is difficult to accurately predict the pore size and distribution of the reservoir, the determination of particle size is blind, and the protection technology established according to the average pore size is difficult to block the large pore throat and the number of small pore throat, which contribute to the production, and the reservoir damage is still serious. Inspired by the surface structure, function and principle of lotus leaf, Jiang guancheng and his team have created a reservoir protection technology of "fiber bridging-particle support-inert membrane barrier" with international leading level. through the principle of "self-identification, self-adjustment and self-adaptation", the defect of accurate prediction of reservoir pore size and distribution is overcome, and the average protection effect is improved to more than 98%. In 1999, he published a seminal paper that first improved the technique of particle inlay protection. The solution proposed in this paper is not only innovative in theory, but also verified in the field test in Dawanqi area of Tarim Oilfield. The results have far-reaching impact, and subsequent researchers' research on reservoir protection technology is based on this in-depth expansion. From practice to practice, Jiang Guancheng, who tasted the innovative sweetness of "learning from nature", realized that nature is the best teacher, and there are endless wisdom and solutions in nature, and this concept runs through his subsequent academic exploration and technological innovation. With the idea of better exploring the mysteries of nature and applying it to engineering practice, in 2001, he entered Ocean University of China to continue his doctorate, learning from nature, and integrating multidisciplinary knowledge for oil drilling has become his increasingly clear goal. At the same time, Jiang Guancheng's exploration in practice continues. Through continuous accumulation and innovation of technology, he and his team have also made many beneficial attempts, including optimizing monomers containing amide groups, ester groups and other functional groups, using emulsion polymerization method, and inventing micro-nano emulsion plugging agent with core-shell structure, forming inert membrane barrier on the well wall through electrostatic force and chemical bonding force. Organic amine fibers and hydrophobic nanoparticles co-invented, under harsh working conditions, a high-strength sealing band is formed to prevent fluid intrusion. In addition, in order to solve the problem of reservoir damage in oil and gas development and production, they have developed controlled hydrolysis well repair protection technology, water injection well polarization protection technology, sand reservoir sand control protection technology, etc., to protect the reservoir and improve the production of oil and gas wells. Based on a series of technologies, they have created the "theory and technology of reservoir damage prediction, protection and evaluation in the whole life cycle of oil and gas wells" with completely independent intellectual property rights, and have successfully realized the transformation of achievements and the popularization and application of industrialization scale in China's major oil fields. The results were applied on a large scale in 11628 wells in 35 oil and gas fields in 12 countries from 2004 to 2006 and 2013 to 2015, increasing production by more than 1.5 times and creating an efficiency of 4.035 billion billion yuan, becoming the main technology for increasing storage and production. This series of technological breakthroughs is also the main support for him and his unit to win the second prize of the National Science and Technology Progress Award in 2007. The first completion of the project is Jiang Guancheng, and the first completion unit is China University of Petroleum (East China). Both "firsts" are in China University of Petroleum (East China), setting a new record since the establishment of the school.

　　Learn from nature and empower drilling

　　In 2009, with a series of innovative achievements in his professional field, Jiang Guancheng received an olive branch from China University of Petroleum (Beijing) and embarked on another exploration journey. China University of Petroleum (Beijing) has become a highland for petroleum science research with its profound academic background, rigorous research attitude, and open academic atmosphere. It provided Jiang Guancheng with a broader stage for scientific research and practical experience. Shortly after arriving in Beijing, Jiang Guancheng received support from the National Science Foundation for Distinguished Young Scholars, becoming the third professor in China's petroleum engineering field and the first professor in the field of oilfield chemistry to receive funding from the National Natural Science Foundation for Distinguished Young Scholars. During the period from the 11th Five Year Plan to the 13th Five Year Plan, he successively became the person in charge of a key project of the National Natural Science Foundation of China, the chief expert of the "863" project, and the only project leader of the "13th Five Year Plan" National Science and Technology Major Special Projects in the field of energy such as oil and gas in Chinese universities. In response to the unique characteristics of different unconventional oil and gas wells, he led his team members to deeply explore and study the technologies and methods suitable for oil exploration and development in nature based on their previously accumulated knowledge of bionics and other disciplines. After more than ten years of continuous research, he overcame a series of technical difficulties and became one of the leaders in new theories and technologies for protecting reservoirs and complex oil and gas drilling fluids, as well as the original creators of theories and technologies for biomimetic drilling fluids and dual porosity drilling fluids.

　　▲Expert research on drilling sites in Xinjiang

In nature, the surfaces of many animals and plants have amazing self-cleaning properties. They can keep clean without external intervention. For example, the surface of lotus leaves can repel water droplets, the leaves of rice and taro leaves, and the wings of butterflies and the feet of water striders all show similar magical phenomena. This phenomenon is called superhydrophobicity, which gives these biological surfaces a special "non-stick" ability. In his early years, Jiang Guancheng dabbled in relevant research and accumulated valuable experience in the study of particle inlay protection technology. After arriving in Beijing, based on the funding of the National Science Foundation for Distinguished Young Scholars and other projects, he continued to expand related research and achieved innovative breakthroughs. Taking the porous medium oil and gas reservoir as the research object, he found that there is a special wetting phenomenon on the surface of the oil and gas reservoir under special circumstances-double hydrophobic (that is, the phenomenon of hydrophobic and oleophobic), and then put forward the definition of double hydrophobic wettability on the surface of the underground rock. Can we solve the problem of "drilling complexity and reservoir damage" encountered in the drilling process by using the characteristics of double dredging in nature? With this idea in mind, he and his team have gained "a precious gift from the integration of nature and the scientific community"-they have established two evaluation methods for double-thinning of oil and gas reservoir rocks, revealed the surface properties and imbibition law of double-thinning rock samples, and put forward the mechanism and control method of double-thinning inversion, the effect of single straight capillary gas-water system displacement characteristics and double hydrophobic on the gas-water-oil distribution characteristics in porous media is clarified, thus creating the theory of double hydrophobic on the surface of the underground formation rock. Based on the theory of double sparseness on the surface of underground formation rock, aiming at the particularity of different unconventional oil and gas wells, Jiang Guancheng led the team to put into practice and verified, and reaped one real innovative fruit after another: the invention of super-hydrophobic strong plugging and high-efficiency tight oil and gas well drilling fluid, which makes the well wall rock appear super double sparseness and inert in the harsh underground environment, and then makes the inhibition reach the oil-based drilling fluid level (highest level), the downhole complexity rate was reduced by 82.9, the speed was increased by 32.8, and the output was increased by more than 1.5 times. Due to its technical advantages, it was introduced by the famous Schlumberger Company, which solved the technical problems that they were difficult to solve. The invention of double hydrophobic polymer membrane strong sealing drilling fluid for coalbed methane wells has solved international problems such as micro-nano pore seam sealing and coal cuttings bed. Compared with international advanced technologies, the thickness of coal cuttings bed and the accident rate of well collapse were reduced by 83.3 and 92.6 respectively, and the output was increased by more than 2.1 times. The invention of high-density soil-free oil-based drilling fluid with hydrophobic type strong plugging shale oil/gas wells solves major international problems such as damage to borehole wall rocks and slow drilling speed by self-absorption. Compared with international advanced technologies, the downhole complexity rate and drilling cost are reduced by 87.6 and 38.22 respectively, and the speed is increased by more than 2.29 times. The achievements have provided drag reduction and blocking and damage prevention technologies for the construction of Sulige's world-class super-large, Linxing-Shenfu hundreds of billions of square meters of large tight gas fields; provided technical support for leak prevention and collapse prevention for the construction of the world's largest conglomerate oil field in Mahu; and provided collapse prevention, drag reduction and damage prevention technologies for China's first Changning-Weiyuan ultra-high pressure complex shale gas field with an annual output of 10 billion cubic meters; for the Qinshui Basin to build China's largest CBM field to provide production-increasing drilling fluid technical support ...... As more and more achievements go to the world's major petroleum projects, the innovative technologies developed by Jiang Guancheng and his research companions not only take root in domestic and foreign oil fields, but also provide a Chinese solution for the sustainable development of global energy, demonstrating Chinese wisdom and strength. The theoretical results of the double-porosity of the rock surface of the underground formation were invited to be edited into the "Theoretical Basis of the Double-porosity of the Rock Surface of Porous Media Oil and Gas Reservoirs (Chinese and English versions)", and some of the theoretical results of reservoir protection were compiled into the petroleum engineering textbooks of American universities, which were highly appraised by academicians and experts at home and abroad. The achievements have successively won the second prize of the 2012 National Science and Technology Progress Award (ranked seventh), the 2017 ministerial-level scientific and technological progress special prize (ranked first), etc., and also won the 2020 China Patent Gold Award (ranked first). The only Chinese patent gold award won in the field of oil and gas well engineering. "Nature is really the greatest designer. It has unlimited innovation potential, waiting for us to explore and utilize." When the pace of exploration became deeper and deeper, Jiang Guancheng also lamented the exquisite structure and survival strategies of natural creatures. The adaptive characteristics evolved by these creatures over a long period of time provided him with endless inspiration and enlightenment. When he was studying for a doctor's degree in Ocean University of China, the characteristics of marine mussels were the first to introduce bionics into the field of drilling and completion fluids, the theory and technology of creating bionic drilling completion fluid foreshadows. Multi-branch, fishbone and other complex structure wells are internationally recognized as advanced well types and main technical development directions for efficient oil and gas development in the 21st century, but problems such as well collapse, high friction, lost circulation and reservoir damage are more prominent and have not been solved for a long time, which has become a worldwide technical problem of drilling and completion fluid and the key to the success or failure of drilling complex structure wells. In order to meet the drilling needs of complex structure wells, the original drilling completion fluid usually contains sulfonated, oil and other toxic treatment agents, which is very destructive to the natural environment and ecosystem. Can we use the characteristics of marine mussel secretion adhesion protein and earthworm secretion mucus to cement rocks and lubricate channels to solve the problems faced in drilling complex structure wells? Jiang Guancheng, inspired by nature's biological way of living, did what he said and started in-depth exploration-through years of accumulation, he cracked the principle of these biological cementing rocks and lubricating channels, grafted functional groups onto special polymer chains, and invented a bionic wall fixing agent that can form a "bionic shell" on rocks, enhance cementing force and improve the mechanical stability of borehole walls. He also developed a bionic bonding lubricant that can bond with the surface of rock and drilling tools, transform the direct friction between drilling tools and borehole wall into sliding between adsorption films, and greatly reduce friction resistance, and then created the theory of bionic drilling completion fluid, as well as new technologies of environmental protection, enhanced borehole and super-lubricating bionic drilling completion fluid. Among them, the bionic solid wall agent can enhance the cohesion between rock particles, so that the strength of the surrounding rock of the borehole wall not only does not decrease but increases, and prevents well leakage, while the most advanced foreign technology can only slow down the decline of rock strength and cannot strengthen the borehole wall; The bionic bonding lubricant can prevent eddy current in the flow boundary and reduce the friction between drilling tool/casing and drilling tool/borehole wall. Compared with foreign technologies, it is more effective in reducing the frictional resistance of the flow boundary. Results application effect is remarkable. From 2013 to 2015, the technology has been applied to 1142 wells in 35 oilfields in 12 countries at home and abroad. The complex rates of well collapse, blocking and sticking have been reduced by 82.6, 79.7 and 86.4 respectively, the average drilling speed has been increased by 27.7, the drilling fluid cost has been reduced by 22.9, and the oil and gas production has been increased by more than 1.6 times compared with the previous wells with complex structures, it has effectively solved major international problems such as well collapse, high friction resistance, well leakage, reservoir damage and environmental pollution of complex structure wells, and realized the harmonious and sustainable development of efficient drilling and environmental protection of complex structure wells. It won the second prize of 2016 National Technology Invention Award (ranked first) and so on. "Bionic drilling completion fluid theory and technology" and "double dredging type strong sealing drilling completion fluid theory and technology" jointly contributed to the progress of drilling completion fluid theory and technology, and provided key support for the establishment of the Chinese model "shale revolution. In particular, as an original achievement, bionic drilling completion fluid has attracted wide attention in the international academic community, and has stimulated the upsurge of research on bionic drilling completion fluid worldwide. It not only leads the development direction of new theories, new methods and new technologies in the field of drilling and completion fluids, but also brings innovative vitality to this field.

　　Success is mine, harmonious resonance

　　Spring blossoms and autumn fruits bear fruit, fertile fields are abundant and valleys are plentiful. Over the past 40 years, Jiang Guancheng has weathered storms and devoted himself to research. He has achieved fruitful results in the field of drilling and completion fluid research in China. However, from beginning to end, he did not feel that the achievements belonged to him alone. "Petroleum drilling engineering is a career that requires collective efforts and wisdom to succeed," Jiang Guancheng integrated his life into the trajectory of the country's "five-year plans" one after another. He had long established the belief and consciousness that "success does not have to be mine, success must be mine. Growing together with the national oil drilling industry and the team is something he considers to be proud of for a lifetime. Since the reform and opening up, China has continuously organized national level group level scientific and technological research in the field of oil and gas well engineering, targeting the characteristics of oil and gas exploration and development in each period. A series of important scientific research achievements have been made, gradually narrowing the gap with the international advanced technology level. The teachers and students of the Oil and Gas Well Engineering discipline at China University of Petroleum (Beijing) have always been involved, and after several generations of unremitting efforts, they have not only excellently completed the scientific and technological research tasks, but also created one strong and structurally reasonable innovative research team after another, accumulating unique heritage and culture. Whenever he mentions his team, Jiang Guancheng cannot hide his pride, and the ones he talks about the most are Professor Liu Xisheng and Academician Shen Zhonghou. Academician Gao Deli Academician Li Gensheng and other senior colleagues have left valuable spiritual wealth to the team during the process of hard work.

　　▲On December 16, 2019, experts visited the application of biomimetic completion fluid in shale gas wells in Zhaotong

　　Adhering to the teachings of his predecessors, Jiang Guancheng always adhered to a principle when establishing the drilling and completion fluid research team led by him: not only did he require team members to have superb professional abilities, but also noble moral character. With the support of this concept, the team has successively produced Dr. Deng Zhengqiang, who held important positions in the 10000 meter deep well project, and Dr. Wu Xiongjun, who stepped forward at critical moments to save people from danger. When talking about these students who made him proud, Jiang Guancheng had a relieved expression on his face. In fact, as the leader of the team, Jiang Guancheng was a lifelong veteran and set an example for his team members: during the "13th Five Year Plan" project tackling period, in order to ensure project progress, he never took a vacation and always maintained a working state of 7 days a week. Continuous overload work caused him to experience tinnitus and even severe hearing loss in his right ear, with irreversible symptoms. He also suffered from lumbar disc herniation and other illnesses, but he did not take leave or rest because of this. He continued to work every day, even when his condition was severe enough to require hospital treatment. He worked in the morning, took time to treat in the afternoon, and returned to work in the evening... Faced with the difficulties of tight personnel and heavy teaching and research tasks, he innovated his work methods, organized team members to actively communicate and exchange ideas, and focused on solving a number of key technical problems in drilling and completion fluids for complex structural wells, achieving fruitful results. In the eyes of team members, Jiang Guancheng is a very special existence with his own unique philosophy - he insists on the independence of thought and encourages team members to maintain an open and innovative spirit in scientific research exploration; He advocates for in-depth research, but when faced with difficulties, he does not stick to one method, but flexibly changes his thinking and seeks new solutions; He emphasizes interdisciplinary collision and integration, applying knowledge from different fields to the field of oil drilling. It is worth mentioning that the concept of "learning from nature" has always been integrated into his and his team's work. Jiang Guancheng always believed that harmony and balance in nature are the source of inspiration for solving complex problems. So he has always encouraged team members to observe natural phenomena carefully, learn biological survival strategies, and discover new ideas and methods to solve problems. This method of drawing inspiration from nature and applying the adaptability, efficiency, and innovation of organisms to scientific research has opened up a new world for them. Finding inspiration for design from the intricate structures of organisms, comprehending the wisdom of collaborative work from the balance of ecosystems, and understanding the importance of adaptation and evolution from the laws of natural selection... These inspirations from nature have been cleverly integrated into the scientific research work of drilling and completion fluids by Jiang Guancheng, enabling his team to not only make technological breakthroughs but also reach new heights in philosophy, giving them more confidence and courage when facing unknown challenges. With the gradual opening of a new round of national petroleum strategic planning blueprint, a new melody of harmonious resonance between technology and nature is playing.
