摘　　要：新场沙溪庙组气藏是西南油气田的主力气藏之一,目前已步入中后期产量递减阶段,随着开发调整的进行,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。提出的优化技术在CX606等7口井中应用成功,施工成功率100%,且均未出现井间干扰,增产效果好,为新场沙溪庙气藏加密调整井的压裂开发提供了一种有效的技术手段。Xinchang shaximiao gas reservoir is one of the main gas reservoir in southwest field,which has entered intermediary and later stage of production decline at present.Parameters optimization of infill well fracturing has been proposed for post fracturing response to guarantee fracturing effects,includeing target fracture length,gravel inputting scale,pre-liquid ratio,average sand ratio,and delivery capacity after development adjustment applications.Optimiza-tion technology is successfully applied to seven wells such as well CX606,which success rate is 100%.Good effect of increase production has been acquired by the technology with-out well interference providing an effective technology for infill well fracturing in xinchang shaximiao gas reservoir.
