Drilling fluid mud cake performance evaluation instrument (ZN-4A)

There is no qualitative standard for the definition of the hardness of drilling fluid mud cake. According to the physical definition of hardness, the hardness of the mud cake is defined as the ratio of the pressure (the default value is 7.5N) to the actual deformation of the mud cake (in 0.1mm). The mud cake hardness is quantified to facilitate the comparison of different mud cake hardness.
