苏里格气田水平井主要压裂施工模式有两种:多级分段压裂和水力喷射压裂。由于采用不同的施工工艺和各种类型的压裂液使得气井水平井施工难度大,施工周期较长,一旦发生砂堵会导致一系列的困难,必要时需要动用连续油管车等特种设备作业。因此,预防水平井的砂堵显得尤为重要,本文就针对苏里格气田水平井的施工,分析并总结出预防及处理砂堵的方法,为今后的施工提供一定的理论和实践指导。
There are two main fracturing modes for horizontal wells in the Sulige gas field: multistage fracturing and hydraulic jet fracturing. Due to different construction technology and various types of fracturing fluid, it is difficult to construct horizontal well in gas well and the construction period is long. If sand blockage occurs, it will lead to a series of difficulties. If necessary, it will need to use special equipment such as coiled tubing car. Therefore, it is very important to prevent sand blockage in horizontal wells. In this paper, based on the construction of horizontal wells in the Sulige gas field, the methods of preventing and treating sand blockages are analyzed and analyzed, which will provide some theoretical and practical guidance for the future construction.
