    摘要:

    卡钻的处理方法主要有:通过施加外力如上提、下放钻具转动转盘使钻具恢复自由状态;通过调整钻井液性能、打稠塞、注酸、注解卡剂、反循环等方法使被卡钻具与井壁之间的填充物转移或者破坏;通过反丝钻具打捞甚至套铣起出被卡钻具。大牛地气田DPT-305水平井通井过程中发生一起严重的卡钻事故。通过重浆+清扫液、注酸、注解卡剂、环空憋压等方法处理被卡钻具与井壁之间的填充物;通过固定转盘上下活动来对被卡钻具施加扭矩;倒扣等方式处理这起卡钻事故,最终解卡。总结了事故的成因,分析了处理过程的得失,为以后处理此类事故积累了经验。

    Abstract:

    The related treatment methods of sticking are mainly by up-lifting and down-lowering drilling tool or rotating turntable with external force to make drilling tool to restore free state; by adjusting drilling fluid performance, putting condensed slurry plug, acid injection, grouting pipe freeing agent and reverse circulation to move or damage the infillings between the pipes and borehole wall; by the use of reverse thread drilling tools to fish and even by casing milling to pull out the stuck drill. A serious sticking accident occurred in the drifting process in DPT-305 well of Daniudi gas field, and the final stuck freeing was completed by heavy slurry cleaning fluid, acid injection, pipe freeing agent grouting and pressure holding in annular space; by fixing turntable and moving it up and down to apply torque to the stuck drill and by the use of reverse thread fisher. The causes of the accident are summarized and the analysis on the treatment process is made, which could be the reference experience for similar accidents in future.
