摘要为研究深部油气、地热能储层改造中岩石起裂及压裂裂缝扩展规律，自主研制实时高温高应力真三轴压裂试验系统，缩小室内压裂物模试验条件与真实深部储层环境之间的差距。该系统主要用于模拟300 mm立方体岩样在深部储层原位环境下的压裂裂缝扩展行为，并对裂缝扩展过程中应力、位移、泵压、排量、声发射信号等参数进行监测及处理。该系统X，Y，Z三个方向应力最大可加载至88 MPa，试样内部可加温至350 ℃，智能调节的温控模式保证了试样整体的均匀加热，滑溜水作为压裂介质时泵注系统最大泵压为210 MPa（超临界CO2压裂时为120 MPa）。利用该系统完成高温高应力下页岩水力压裂试验及花岗岩超临界CO2压裂试验，试验结果表明：该系统准确性高、稳定性好；高应力下泵压曲线峰后波动加剧；高温降低了页岩破裂压力，并有利于裂缝复杂度提升；超临界CO2作为压裂介质时，花岗岩破裂压力显著降低，声发射信号数量及能级减弱，裂缝复杂度提升。相关研究结果可为深部储层改造工艺优化提供理论及技术支持。

Abstract： To investigate the initiation and propagation of fractures in deep oil, gas, and geothermal energy reservoir stimulation, an independently developed real-time high-temperature and high-stress true triaxial fracturing test system was created. This system bridges the gap between laboratory fracturing simulations and actual deep reservoir conditions. It is designed to simulate the fracturing and fracture propagation behavior of 300 mm cubic rock samples under in-situ deep reservoir conditions. The system monitors and processes parameters such as stress, displacement, pump pressure, flow rate, and acoustic emission signals during fracture propagation. The maximum stress in the X, Y, and Z directions can reach 88 MPa, and the internal temperature of the sample can be heated to 350 ℃. The intelligent temperature control mode ensures uniform heating of the entire sample, and the maximum pump pressure is 210 MPa when slickwater is used as the fracturing medium (120 MPa with supercritical CO2). The system has successfully conducted hydraulic fracturing tests of shale and supercritical CO2 fracturing tests of granite under high-temperature and high-stress conditions. The test results demonstrate high accuracy and good stability. Under high-stress conditions, post-peak fluctuations in the pump pressure curve are intensified. High temperatures reduce breakdown pressure and increase fracture complexity. When supercritical CO2 is used as the fracturing medium, the breakdown pressure of granite significantly decreases, the number and energy level of acoustic emission signals weaken, and fracture complexity increases. These findings provide theoretical and technical support for optimizing deep reservoir reconstruction technology.

Key words： rock mechanics;high-temperature and high-stress true triaxial;fracturing physical simulation;deep reservoir;supercritical CO2
