Product overview

The ultrasonic cement compressive strength analyzer (UCA) is used to detect the development of the compressive strength of cement samples cured under simulated bottom hole temperature and pressure. By measuring the change in the speed of the ultrasonic signal passing through the cement sample when the cement sample hardens, The compressive strength of the cement can be determined. As the compressive strength of the cement increases, the transmission time of the ultrasonic signal passing through the cement sample decreases continuously, the corresponding compressive strength can be calculated by using a proprietary empirical algorithm validated by the oil and gas industry. The cement slurry to be tested is prepared by 4060A constant-speed agitator according to the requirements of Chapter 5 of API 10, then the cement slurry is poured into the cement test mold, and then put into the pressure kettle. The pressure kettle is heated and pressurized to specific oil well conditions. The compressive strength of the sample is measured while the sample is usually cured in the pressure kettle for 8, 12, 24 hours or 7 days.

The entire ultrasonic system of the instrument consists of a pressure kettle and a central processor (personal computer). The computer is equipped with special application software with ultrasonic function.

The ultrasonic system is compact, and the pressure kettle adopts a shockproof chassis structure that has been verified for many years, equipped with an electronic processing board (PCB), a highly reliable industrial microprocessor and special curing software. The central processor is usually based on a personal computer, using a microcomputer WINDOWS operating system to run the company's data acquisition system.
