Rock gas breakthrough pressure testing device

Rock gas breakthrough pressure testing deviceAfter the rock sample is saturated with a wetting fluid, the non wetting fluid must overcome the capillary resistance of the rock in order to displace the wetting fluid. The smaller the capillary radius of the rock, the greater the measured resistance and the higher the required breakthrough pressure. Gradually increasing the test pressure at the inlet under simulated geological conditions, when the pressure is sufficient to displace the saturated fluid in the rock sample, gas breakthrough and escape can be seen at the outlet, and the breakthrough pressure of the rock sample can be measured. According to the formula of Botao Ye (1949), the breakthrough time is calculated as the time it takes for gas to cross from the bottom boundary to the top boundary of the cover layer. This device is used for measuring breakthrough pressure of tight sandstone, shale, and carbonate rock samples. Other samples such as salt rock, gypsum rock, and tuff can also be used as reference.
