摘　　要：本文利用数值模拟软件CMG-STARS模块对缝长,缝宽,导流能力等进行最佳优化,结果表明对产能的影响程度大小依次为:半缝长,裂缝条数,裂缝间距,用这些最优参数制定压裂方案对压后产能的提高具有重要指导意义。This paper uses numerical simulation software CMG-STARS module to optimize crack length,slit width,flowconductivity and fracture heterogeneity.The results show that the impact sequence of these factors to capacity is:half crack length>crack number>crack spacing.And finally these optimized parameters used to make fracturing schemes have an important guidance forthe improvement of productivity after the fracturing.
