在钻探升降操作中,所使用的卡槽提引器,由于在结构上的某些缺陷,在升降时常发生跑管和钻具自提引器中滑脱所造成的人身伤亡或机械损坏事故,严重影响正常工作.为了解决此一工序的安全操作问题,现仅根据以往的资料和我们在生产过程中改进的提引器,作一介绍,希大家参考和指正.改进后的提引器 During the drilling and lifting operation, the used card slot lifter, due to certain structural defects, often causes a personal injury or mechanical damage accident caused by slippage of the running pipe and the drilling tool from the lifter during lifting. Affect the normal work. In order to solve the problem of safe operation of this process, only based on the previous information and our improved extractor in the production process, made an introduction, we refer to and correction. Improvement after the extractor
