| 中文摘要:绳索取心钻进中，钻具断脱常会导致内管总成掉入孔内，打捞内管总成无疑是一个非常棘手的问题。本文分析了存在的施工难点及应采取的施工措施，针对2个钻孔不同的实际情况设计的2套内管总成打捞工具，成功把全部裸露于孔内的内管总成打捞上来，避免了钻孔报废，节约了时间，降低了经济损失。实践证明这2种工具是有效的。 |

| Abstract:The inner tube assembly often falls into the hole due to breaking off of the core drilling string. This paper analyzes the existing fishing difficulties and the measures to be taken, and describes the design of two sets of fishing tool in view of the actual situation of two different drilling holes. The inner tube assembly which was completely exposed in the hole was successfully fished out of the hole, avoiding abandonment of the borehole, saving drilling time, and reducing economic loss. Practice has proven that these tools are effective. |
