摘要
中国国内水平井修井技术远落后于钻井技术,长水平井段水平井修井作业难度极大。在这一背景下,在YS108HX-X水平井处理套变过程中,借鉴多臂井径测井和铅印手段认清井下情况,采用球形磨鞋、套铣筒、三刀翼磨鞋等套管整形工具,并根据井下情况及时调整修井方案,成功钻磨剩余桥塞,为页岩气水平井修井积累了经验。
The domestic workover technology lags far behind drilling technology of horizontal well.Workover in long horizontal well is extremely difficult.Taking YS108 HX-X horizontal well as an example,the remaining bridge plugs are milled,by using multi-arm caliper logging,impression block and various mill shoes.Some experience for shale gas horizontal well workover is accumulated in this case.
