doi:10.7657/XJPG20160217

Abstract

Abstract: To further improve the effectiveness of staged fracturing design for shale gas horizontal well, a comprehensive fracturing stage and cluster optimization method was studied. Based on the results of numerical simulation and fracturing simulation, considering the effect of actual fracture geometry and multi?fracture parameters, this paper presents an orthogonal design method for sectional parameters optimization; after that, it proposes a W?type staged fracturing model for obtaining maximum productivity; according to multiple cluster?fracture stress interference and induced stress distribution, it establishes a more reasonable clustering optimization method; considering the geologic attributes and engineering features in real trajectory of shale gas horizontal well, it provides a comprehensive optimization method of fracturing stage and cluster in terms of geologic long segment and engineering short segment
