摘　　要：在西气东输管道长江穿越工程中,由于江水水深流急,流态紊乱,不利于水上钻探,因此,对钻探工艺的合理性进行了分析,分析结果表明,采取恰当合理的钻探平台形式、定位措施、套管安装技术和钻探方法等,可有效应对各种复杂情况,顺利实施水上钻探。In the Yangtze River crossing for West-to-East gas transmission pipeline project,it is very difficult for above-water engineering and geology reconnaissance due to the swift current and deep water. A rationality to apply the above water engineering and geology reconnaissance method was analyzed. According to the analytical results,a proper and suitable drilling platform,location system and casing pipe were utilized. By means of these effective measures,the successful above-water reconnaissance was made.
