摘要
四川盆地须家河组近年来新增探明储量以致密低渗砂岩气藏为主,单井产量较低,因此通过布置大量的丛式井组来提高经济效益。针对丛式井组规模效益开发配套技术开展了一系列的攻关工作,进行了一系列的技术集成,从液体体系、放喷制度、放喷控砂、液体回收再利用等,形成了西南油气田丛式井组整体试油特色技术。目前该技术进行了大面积的推广应用,取得了较好的增产效果及经济效益。
The incremental proved reserves of Xujiahe reservoir in Sichuan mainly come from tight and low permea- bility sandstone gas reservoirs in recent years, but the production per well is very low. In order to improve economic efficiency, lots of cluster well groups were deployed in this area. We carried out a series of relevant research to support the large scale and cost-effective development of cluster well group including liquid system, venting system, sand control, liquid recycling, etc. The overall test oil technology of cluster well group have formed unique features in southwest oil and gas field. The technology has been applied widely, and achieved good stimulation effect and e- conomic benefits.
