摘　　要：天然气管道穿越河流采用水平定向钻施工中越来越广泛,因为其具有导向准确、综合成本低、工期短等优点,并且技术越来越成熟。结合某省级天然气管道定向钻穿越长江工程实例,介绍定向钻穿越复杂地质条件的主要施工工艺,并对技术难点进行分析。Horizontal directional drilling is more and more widely used in the construction of natural gas pipeline crossing rivers,because it has the advantages of accurate guidance,low comprehensive cost,short construction period,and more mature technology.Combined with a provincial natural gas pipeline directional drilling across the Yangtze River project example,this paper introduces the main construction technology of directional drilling through complex geological conditions,and analyzes the technical difficulties.
