Description

Technical field [0001] The invention belongs to the technical field of petroleum fracturing, and in particular relates to a pulsating load temporary plugging fracturing simulation device and method. Background technique [0002] Temporary plugging fracturing is an important technology to increase the complexity of fracturing fractures and fracture control reserves. It is widely used in the process of fracturing new wells and repeated reconstructions of old wells. The construction effect of temporary plugging is not only related to the performance of temporary plugging materials and temporary plugging. The amount of the agent is directly related to the temporary plugging agent accumulation location, filling degree, etc. The test results of the traditional temporary plugging fracturing simulation device are inaccurate, and the test process cost is high. [0003] Low-frequency hydraulic pulsation uses the pressure vibration wave of the liquid to propagate energy in the liquid, and has...
