Zusammenfassung: | The invention relates to a shale reservoir well factory horizontal well fracturing parameter layering multistage optimization method. The method comprises the following steps that data needed by structure and geological attribute modeling are obtained; completing the corrected earthquake and logging interpretation result; coupling and establishing a reservoir rock mechanical physical property field model by utilizing the single well core and logging mechanical parameters; establishing a three-dimensional crack propagation model in a well platform multi-well fracturing mode by utilizing numerical simulation software; performing main control factor analysis on the parameters by using a sensitivity analysis method; expanding a sample set through an improved Monte Carlo sampling method; and an optimization algorithm is used for the proxy model by using a differential evolution optimization algorithm. According to the multi-stage optimization method, the whole-area fracturing optimization problem is divided into s |
