The purpose is to form a complex fracture network through effective communication between natural fractures and rock bedding, improve the overall permeability of the reservoir, and realize the comprehensive stimulation of the reservoir in the max SRV directions. Cluster perforating technology is an important technology in multi-stage fracturing technology of shale gas horizontal wells. With the deepening of shale gas exploration and development in China, cluster perforation technology has also been developed and widely used. Reasonable clustering perforation of the stages can significantly increase the number of lateral diversion fractures and ultimate EOR. In this paper, by using the comprehensive analysis of the microseismic monitoring results of adjacent wells, the fracturing effect of different cluster number of single stages is evaluated, which provides a certain basis for the next step of fracturing design.
