摘　　要：为了研究高速通道压裂过程中裂缝的导流能力及其变化规律,运用数值模拟方法建立模型就支撑剂柱直径、缝宽、支撑剂柱弹性模量、储层弹性模量、闭合压力等5因素对裂缝导流能力的影响进行了逐一模拟分析。结果显示,缝宽、支撑剂柱弹性模量和闭合压力对裂缝导流能力的影响程度最大,在压裂设计时应引起更多的关注;支撑剂柱直径和储层弹性模量对裂缝导流能力的影响作用相对较弱。研究成果丰富了当前对高速通道压裂技术的研究。In order to investigate the flow conductivity and related factors of hydraulic fracture in channel fracturing,numerical simulation was applied to investigate the influence of such 5 responding factors as proppant slug diameter,fracture width,proppant slug stiffness,reservoir stiffness and closer pressure. Results showed that fracture width,proppant slug stiffness and closer pressure mattered much to the fracture conductivity and they were the important factors to be paid attention to when the hydraulic fracturing plan was being designed. Proppant slug diameter and reservoir stiffness made relatively little contribution to fracture flow conductivity. The results enriched the current research about channel fracturing technology.
