摘　　要：新场沙溪庙组气藏是西南油气田的主力气藏之一。目前,该气藏开发已步入中后期产量递减阶段。随着气藏开发调整的进行,部分压裂井出现井间干扰、压后效果不佳的情况。针对这种情况,提出加密井压裂施工参数优化技术,对加密压裂井的目标缝长、加砂规模、前置液比、平均砂比以及排量等进行优化,以保障加密井的压裂效果。As one of the main gas reservoirs in oil and gasfield of southwest Sichuan Basin,Shaximiao reservoir of Xinchang gasfield is now in the production decline stage.With the development adjusting,both inter-well interference and poor after-fracturing effect appear in some fractured wells.In this paper,a parameter optimizing technology of infill-well fracturing is put forward to optimize the target fracture length,sand scale,pad fluid ratio,average sand ratio and displacement.So that effective fracturing can be obtained.
