High-Temperature and High-Pressure Fracturing Seepage Multi-Field Coupling Simulation Experimental Platform

(1) The confining pressure loading system can independently control the stress path, allowing control and monitoring of the loading rate and deformation rate during axial loading, achieving linked control of principal stresses and setting the stress path; (2) Triaxial independent loading can automatically and independently control the application of axial and lateral loads, avoiding mutual interference while coordinating them, enabling the specimen to bear different magnitudes of normal stress along axial and lateral directions, simulating the true stress state of rock mass, and conducting various true triaxial stress path tests; (3) Automatic measurement and control realize automation of all stress signal input and feedback control, as well as A/D conversion of test and measurement signals and automatic data acquisition and processing; real-time monitoring and acquisition of stress and displacement in the loading system; (4) Using an acoustic emission monitoring system to observe and analyze microcrack events generated during rock fracturing in simulated strata, locating cracks, mapping spatial images of fractures, monitoring fracture development, and identifying fracture characteristics (geometric shape, direction, etc.); (5) Capable of simulating deep rock mass development by injecting fluid media (CO₂, water, heavy oil) into the rock mass, analyzing flow patterns and characteristics in fractures, optimizing mining design and rock mass development, and providing theoretical basis for enhanced geothermal reservoir modification.
