钻井转掘砌快速临时改绞初步探讨 史基盛 中煤特殊凿井（集团）有限责任公司 摘要：本文介绍一种钻井转掘砌的快速临时改绞方法。该方法要求：技术上一是将掘砌用井架基础分成混 凝土基础、钢结构过渡盘两部分，二是在钻井的井口外组装掘砌用井架，而后在钻井的壁后充填结束后平 移到井口。工程计划管理上要实行网络计划法，严格控制各工程的时间节点，将掘砌用各基础施工、井架、 绞车、稳车等设备安装调试时间穿插到钻井作业中平行进行，从而达到快速改绞的目的。采用该方法改绞 可比钻井施工结束后再进行改绞提前时间60天以上。 关键词：钻井；掘砌；临时改绞；快速；初步探讨 The Drilling Turns To Dig Quickly To Change To Temporary Promotes An Initial Study SHI Jisheng China Coal Special Drilling Engineering(GROUP) Corporation Limited Summary: This text introduces a kind of drilling to turn to dig quickly to change to lift a method.That method request:In the technique on being to will dig well foundation to be divided into concrete foundation, the steel structure transition dish two parts with the foundation, two is a construction to dig to use a well outside the mouth of a well of the drilling, even move to mouth of a well after and then filling to end after the drilling of wall.The purpose wanted to carry out a network plan method in the engineering plan management, strictly controled the time node of each engineering, dig to carve to adjust to try time to add parallelism in the drilling homework to carry on with the each foundation construction, well, winch, steady car etc. the equipments parallel gearing, attained thus to quickly change to wring.Adopt that method changes to wring and can compare the empress of the be over of drilling construction again carry on changing to wring more than 60 day time in advance.
