Overview

       Under the condition of simulated formation,the physical simulation experiment of the cover layer,temperature,pressure and other single factor capping layer is carried out,and the maximum pressure test of the gas breakthrough rock sample is carried out.The device is used to study the sealing ability of the cover under different conditions,the damage mechanism of the pressure on the reservoir and the test of the stress sensitivity of the cover(keep constant confining pressure and reduce the internal pressure),and study the stress sensitivity of the cover.
