中文摘要:在历年的钻探施工中,由于地层原因造成埋钻或处理烧钻、卡钻时间久衍生埋钻事故,使用常规的套铣方法处理,工人的劳动强度大,公锥等材料消耗多,并且成功率低,容易产生弃孔损失。本文介绍了使用超长套铣筒处理鄂尔多斯盆地铀矿钻探中埋钻等孔内事故的方法,可大幅度缩短处理事故的时间,降低工人的劳动强度,提高机台的本质安全度,降低报废钻孔的概率,为今后钻探施工中处理埋钻等孔内事故提供一种比较快速、安全的处理方法。

Application of the extra-long washover pipe in bit burial treatment in uranium drilling in Ordos Basin
Abstract:In the drilling operations over past years, conventional washover milling has been used to deal with bit burial due to the formation or a long time treatment of bit burning or sticking. This method is labor-intensive and consumes materials such as male cones with low success rate, even scrapping of the borehole. This paper introduces use of the extra-long washover mill to deal with down-shole accidents such as bit burial in uranium drilling in Ordes Basin. It can greatly shorten the treatment time of the accident, reduce the labor intensity, improve the intrinsic safety of the drill, and reduce the abandonment rate of holes. It provides a fast and safe method for dealing with down hole accidents in future drilling operations.
