According to previous studies, fault slip in shale gas fracturing is the main factor leading to the shear deformation of casing in horizontal Wells of shale gas. How to evaluate fault slip is crucial to the fracturing effect of horizontal Wells. At present, fault slip analysis mainly focuses on the study of models without a relatively complete evaluation process. Researchers have carried out a lot of exploration work and formed a fault slip evaluation technology based on three-dimensional seismic data. The main method is to apply fault and ground stress modeling methods and calculate the maximum critical injection pressure of faults according to the Coulomb fracture criterion to evaluate the fault slip, so as to reduce the risk of fault slip caused by the fracturing process. The results show that the slippage is determined by the magnitude, direction and occurrence of faults.
