Device and method for testing physical and mechanical properties in formation hydrothermal pressurization process

The invention belongs to the technical field of petroleum engineering, and particularly relates to a device and a method for testing physical and mechanical properties in a formation hydrothermal pressurization process. The device comprises a bracket, a computer system, a rock core pressing mold and a reaction kettle, and further comprises an acoustic emission signal processing unit, a displacement sensor, an axial pressure loader, a liquid supply and drainage device, a gas supply and exhauster, a temperature controller, a confining pressure controller and a pore pressure controller which are all controlled by the computer system. According to the test method provided by the invention, the actual condition of the stratum can be simulated, the rock debris sample is utilized to analyze the influence of temperature rise on the pore pressure at the preset temperature and pressure, the elastic modulus and the Poisson's ratio are calculated, and the stratum pressure is predicted. The device is simple to operate, ca
