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 control the reserves of fractures. It is widely used in the process of fracturing new oil and gas wells and repeated reconstruction of old wells. In addition to being directly related to the dosage of the temporary plugging agent, it is also related to the accumulation position of the temporary plugging agent and the degree of compaction. The test results of the traditional temporary plugging fracturing simulation device are not accurate, and the test process is costly. [0003] Low-frequency hydraulic pulsation uses the pressure vibration wave of the liquid to propagate energy in the liquid, and has certain applications in the fields of in...
