Overview

       The porosity and permeability of oil and gas reservoirs are related to rock compression degree besides rock structure and construction.The pressure strength acting on the reservoir is caused by the overburden weight.The device is mainly used for testing the porosity and permeability of rock samples under the condition of overburden pressure.
