Optimization design method for intimate cutting fracturing non-uniform perforation of deep shale gas horizontal well

The invention discloses an intimate fracture non-uniform perforation optimization design method for a deep shale gas horizontal well, relates to the technical field of shale gas development, and is specially used for an intimate fracture non-uniform perforation process for the deep shale gas horizontal well. A deep shale horizontal well fracturing hydraulic fracture initiation extension model, a single-cluster perforation hole flow friction resistance pressure drop model and a perforation hole number optimization model are established; according to the method, the influence of the stress interference effect between the fractures on the extension of the hydraulic fractures of each cluster during close cutting fracturing of the deep shale horizontal well is fully considered, so that the number of the holes of each cluster of non-uniform perforation is optimized and adjusted, the extension half lengths of the hydraulic fractures of each cluster tend to be consistent, and the targets of'growth restraining, shorte
