摘要
针对水平定向钻穿越施工中出现的问题,分析了水平定向钻穿越施工导向孔在钻进过程中偏离设计穿越曲线的一些原因,并根据施工经验总结出减少导向孔曲线与设计穿越曲线偏差的一些施工方法。
This paper had analyzed the causes of pilot hole＇s deviation from designed crossing curve during horizontally directional drilling for pipeline crossing,furthermore summed up some measures to reduce the deviation between pilot hole＇s curve and designed crossing curve based on the construction experiences.
