几年中，我们地质队在驻地附近为地方部门和社队施工了不少机井，同时也常帮助各单位，打捞深井泵脱管等事故，从近二年的实践中对比，我们认为打捞深井泵所用的工具以抓卡式钻具比较适用，现介绍如下。一、打捞泵管钻具所用钻具如图1，从下至上组成部件有抓卡式钻头，岩心管，岩心管接头，钻杆等。除抓卡式钻头外，其岩心管、岩心管接头和钻杆均为岩心钻探普通管材，不需另加工。
In recent years, our geological team built quite a number of machineries for local departments and social teams near the station. At the same time, we often helped various units to salvage deep-well pumps to take off pipes. Compared with the past two years, we believe that the recovery of deep wells The tools used by the pump to grasp the card-type drilling more applicable, are described below. First, the recovery of the drill pipe used in drilling tools Figure 1, from bottom to top components have grasping card drill, core pipe, core pipe joints, drill pipe and so on. In addition to grasping card drill, the core pipe, core pipe joints and drill pipe are core drilling ordinary pipe, without additional processing.
