摘要
新疆油田夏9井区A油层开发中遇到的最大问题是油层上部隔层薄,裂缝缝高难以控制,严重影响压后效果。在水力压裂缝高延伸影响因素分析基础上,采用上浮剂形成人工遮挡层阻止裂缝向上延伸,同时优化射孔和压裂施工参数,形成了夏9井区控缝高压裂配套技术。13口井现场应用表明,该技术能够有效控制缝高延伸,提高压裂效果。
The top interlayer of A reservoir is very thin in Xin-jiang Oilfield Xia 9 block,so,the control of fracture height is diffi-cult. Based on the analyzing influential factor on fracture height ex-tension ,the complex control fracture height technology was estab-lished,including artificial barrier bed technology,as well as perfora-tion and fracturing parameters optimization technology. The technolo-gy could control effectively fracture height and improve postfracture response by field test to 13 wells.
