Overview

        Determination of capillary pressure and electrical properties of rocks is one of the important measures to study the physical properties of rocks and the seepage properties of multiphase fluids in rock pores.The capillary pressure and electrical coupling measurement system adopts imported semi permeable (over water and no air) baffle,and the test pressure can be increased to 10MPa.The electrical property of rock can be measured online while measuring capillary pressure.The device can simultaneously measure 3 samples and it is controlled by a computer. According to the requirements of the test,the capillary pressure,the volume of the discharge liquid,the water saturation and the resistance value under this state are timed itinerant then the data is automatically saved.When the liquid is no longer discharged at every pressure point,the instrument will alert the test to the next pressure point.
