| Abstract:In the drilling process of ZK1010 which is a deep exploration hole of Yuquan manganese mine in Xiushan of Chongqing, drill pipe breaking often happened. Drill pipe falling often occurred during tripping out process, which made the accidents even worse. Finally, by the use of releasing fishing spear, the drill rod breaking is successfully handled for times. The paper introduces the releasing fishing spear about its working principle and advantages. |
