Ultrahigh-temperature and high-pressure device and method for simultaneous measurement of rock sample resistivity and capillary pressure

The invention belongs to the technical field of geophysical logging, and particularly relates to an ultrahigh-temperature and high-pressure device and method for simultaneous measurement of rock sample resistivity and capillary pressure. Comprising a case, a rock core clamping module arranged in the case, a test module communicated with a fluid inlet end and a fluid outlet end of a rock core to be tested, and a constant temperature module arranged in the case and used for adjusting the temperature of the test module, the rock core clamping module is used for clamping a rock core to be tested, the temperature control module is connected with the rock core clamping module and used for controlling the experiment temperature of the rock core to be tested, and the monitoring module is used for collecting and recording experiment parameters. The pipeline of the test module and the pump are integrated into the constant temperature module, and the temperature control module is mounted in the rock core clamping module
