摘要
井筒检查孔施工时对主要含水层进行分层抽水试验,需要进行多次起、下抽水套管作业,给井筒检查孔的施工增加了难度。针对这一问题,通过对塔什店矿区一号矿井主、副井井筒检查孔施工过程中出现的抽水套管粘卡、滑落等事故处理方案进行分析总结,提出了一系列的处理及预防措施,为今后类似工程的施工提供一定的借鉴。
During the construction of the cylinder inspection hole, the main aquifer is stratified pumping test, which needs to be carried out many times, and the operation of the pump casing, which increases the difficulty of the construction of the hole in the wellbore.In order to solve this problem, through the Tashidian area a number of mine main, auxiliary shaft check of hole construction process of pumping casing sticky cards, falling off accident treatment scheme were analyzed and summarized, put forward a series of treatment and prevention measures, provide certain reference for the future similar project construction.
