| 摘 要： | 复合桥塞具有容易钻铣、钻铣时产生的碎屑轻小、不易卡钻等优点。通过桥塞坐封和射孔联作,不但缩短了水平井分段压裂的施工周期,利用其内部单流阀结构,还能实现压裂后的迅速返排、快速投产。复合桥塞应用于江汉建页HF-1井水平井分段压裂,效果理想,封堵隔离作用好,压裂施工中没有漏失和移位现象。

| Abstract: | Composite bridge plug is easy to drill and mill.It produces lighter and smaller chips while drilling and milling and no sticking occurs.Combining bridge plug setting with perforating is able to shorten operation period for staged fracturing of horizontal wells,and in another,using its internal single-flow valve structure is likely to realize a rapid flowback after fracturing and fast production.The application of composite bridge plug in Jianghan Jianye HF-1 horizontal well has yielded desired result in plugging and buffering with no leakage and shifting occurring in fracturing. |
