摘要:
苏里格地区分层压裂使用的投球滑套需要与压裂球进行匹配，但在压裂管柱上存在多处缩颈，导致后期测试工具无法下入。可溶解滑套将接球座内部的支撑套设计成可溶材料，其外部包裹一层橡胶薄膜，滑套下入后，性能稳定，只在压裂过程中高速液体将其薄膜破坏使可溶材料与井筒内液体接触时，发生溶解反应，实现压裂管柱无缩颈。10口井现场应用表明，在不改变施工工艺的情况下，支撑套溶解，滑套芯子落入井底实现压裂管柱的全通径，能够满足后期冲砂、测试、监测产液剖面等作业需要，具有一定的推广前景。
Abstract:
The sliding sleeve used in separate layer fracturing in Sulige area needs to match with the fracturing ball, but there are many necking phenomena on the fracturing string, which leads to the failure running of later testing tools. The dissolvable sliding sleeve is designed with a soluble material inside the support sleeve of the ball catcher. The outside is wrapped with a layer of rubber film. After running the sliding sleeve into the hole, the sliding sleeve has stable performance. Only after the highspeed liquid destroys the film in the fracturing, the soluble material will dissolve when contacting with the liquid in the wellbore, so that there will be no necking of the fracturing string. The field application in 10 wells shows that, without changing the construction technology, the support sleeve dissolves and the sliding sleeve core falls into the bottom of the well to realize the full diameter of the fracturing string, which can meet the needs of sand washing, testing and monitoring the production profile in the later stage, and has a certain popularization prospect.
