摘要
ＣＣ１科学探索井最大钻深５２８５．８６ｍ，下钻划眼至井深５０５３．１６ｍ时发生钻具落井事故。用ＺＪ４５钻机一次性成功地打捞起长达５０４３．１６ｍ的多段落井钻具，属国内首次。文中较为详细地介绍了该井打捞作业难点、钻具事故处理程序、打捞工具，分析了钻具事故原因。这次事故的处理成功挽回了８７万元经济损失，为该井下步钻探提供了保证。
After CC1 scientific exploration well was drilled to the depth of 5285. 86 meters, as long as 5043. 16 meters drill string was lost into the well. The fishing operation was successfully finished with ZJ45 rig. In this paper, the difficult problems,the method and tools of the fishing operation are introduced.
