摘要
在CH137井打捞井内腐蚀油管的大修井作业中,运用了多种修井工具和工艺技术。针对井内落鱼的不同形状,先后多次通过强提、倒扣相结合的复合打捞方法,顺利打捞出3687 m以上油管,为最终完成修井任务和解放油气层争取了时间。其独特的修井思路和成功应用对今后大修井作业具有很高的参考价值,对处理类似事故起到了一定的借鉴作用。
In well work-over operation to fish corrosion tubing in CH137 well,kinds of workover tools and technology were used.According to different shapes of fish in the hole,many combined ways of pulling heavily and back-off have been applied to fish 3678 meters of tube which makes true having time to complete work over job and releasing oil layer and gained a good result.
