The present invention relates to a rock physico-mechanical testing chamber and a three-dimensional multi-field information perception cabin in simulated environments of deep earth, deep space, and deep sea. The testing chamber comprises a cabin body and 6 butting indenters; the 6 butting indenters are pairwise located in an X-axis direction, a Y-axis direction and a Z-axis direction; the 6 butting indenters are respectively mounted in through holes on six faces of the cabin body, inner ends of the butting indenters extend into the cabin body, outer ends of the butting indenters are exposed out of the cabin body, and the butting indenters can axially move relative to the cabin body. The present application can be used to achieve the reservoir rock mechanical behavior testing in real time under high and low environments.

The present invention relates to a deep rock in situ environment reconstruction and integrated three-dimensional mechanical-thermo-acousto-seismic-flow testing method, which comprises: preparing a cubic sample; placing the cubic sample in a sample holder; extending the 6 indenters to butt with the sample holder; butting 6 butting indenters with the 6 indenters; butting each of 6 hydraulic actuators with one of the butting indenters, performing stress loading on the cubic sample by the hydraulic actuator, filling a fluid medium into the cubic sample by a percolation medium channel, and dynamically measuring related parameters. The present application can achieve three-way multi-parameter synchronous monitoring and acquisition of deformation, acoustic emission, ultrasonic wave, temperature field, percolation field and heat flow field.
