卡钻是油井修井作业中常见的一种事故,修井作业本身具有一定难度,同时受到地质构造和钻井液性质、岩层特性以及相关设备的影响,再加上操作人员的失误等因素使得油井修井工作更加困难。造成卡钻的原因很多,本文针对油井修井卡钻的类型以及原因展开分析,提出了相应的解卡措施,有效的防治油井卡钻,提高修井的效率,使油井尽快恢复正常运行。
Drill-sticking is a common accident in oil well workover. The workover work itself has some difficulties. At the same time, due to the influence of geological structure and drilling fluid properties, formation characteristics and related equipment, coupled with operator errors, Workover work more difficult. There are many reasons for the stuck drilling. In this paper, according to the types of oil well workover stuck and the reasons, this paper puts forward the corresponding measures to solve the problems, effectively prevent and control the stuck oil well, improve the workover efficiency and make the oil well resume normal operation as soon as possible.
