Short summary
A THMC multi-field rock resistivity test system is developed, which has the functions of rock triaxial and resistivity testing under the conditions of high and low temperature, high pressure, and high salinity water seepage. A sealing method to prevent the formation of a water film on the side of the specimen is proposed based on the characteristics of the device. The device is suitable for studying the relationship between rock mechanical properties and resistivity in complex environments.
