摘要
随着螺旋钻进技术在松软突出煤层中的推广应用,螺旋钻杆打捞工具也不断发展。介绍了打捞丝锥、钻筒打捞器以及由煤炭科学研究总院西安研究院设计并生产的扩孔式螺旋钻杆打捞器3种常用螺旋钻杆打捞工具的结构特点及工作原理。
With the generalization and application of spiral drilling technology in loose and soft seam which prone to outburst, fishing tools for spiral drilling rod are also growing up . This paper introduces the structural characteristics and principle of three kinds of fishing tools for spiral drilling rod, which are fishing tap,fishing pipe and reaming-type fishing tools ,and the third is designed and produced by Xi＇an Branch of China Coal Research Institute.
