- 铁秦线羊肠河定向钻穿越位于辽宁省黑山县羊肠河,文章以该穿越工程为例,对定向钻施工几个重要参数:直推压力、旋转扭矩、回拖压力进行了分析,详述了穿越中导向孔、扩孔、回拖施工过程以及本次施工中遇到的困难和解决办法。
The project of Yangchanghe River crossing with horizontal directional drilling is located at Heishan County,Liaoning Province.Taking this crossing project for example,this paper analyses several key parameters,i.e.pushing pressure,rotary torque and back dragging pressure,expatiates on the construction courses of pilot hole drilling,hole reaming and back dragging,as well as the difficulties encountered in this crossing construction and the solutions.2009,4(4): 34-37 收稿日期：2009-2-23分类号：TE973.4作者简介：曹晓东(1968- ),男,辽宁盘锦人,工程师,1993年毕业于西安石油大学焊接专业.从事石油工程监理工作参考文献：
