1. a physical simulation system for fracture propagation in shale, including:

  • Rig, it is in the prefabricated simulation well in the pre-position of shale sample to be simulated;

    Sealer, it adopts the sealing gap between the encapsulant analogue perforation sleeve pipe to putting in described simulation well and described simulation well;

    Lathe, it is prefabricated monitoring holes on the end face of multiple load plate;

    True triaxial physical simulation experiment machine, the pressure break sample putting into its three axles loading chamber is simulated the loading of three-dimensional crustal stress by it, and described pressure break sample is be loaded the shale sample to be simulated after described rig and sealer process that plate holder is held;

    Fracturing servopump pressure control system, it provides fracturing fluid to simulate hydraulic fracturing process to described pressure break sample;

    Acoustic emission three-dimensional fix monitoring equipment, described simulation hydraulic fracturing process is monitored by real time;

    Industrial CT Machine, the pressure break sample before and after fracturing is carried out profile scanning by it.
