油气管道的河流穿越技术进展

River Crossing Designs of Petroleum and Natural Gas Pipelines

综述了油气管道河流穿越技术的发展历程和各种穿越施工方法,比较了沟埋、定向钻、隧道等穿越技术的优缺点,并列举了部分工程实例;分析了各种施工方法适用的范围和条件,并提出施工中应注意的问题,对实际设计和施工具有一定的借鉴意义。

With the construction of the natural gas transmission pipelines running from Sichuan Province to East China and from Yulin to Jinan,as well as the second natural gas transmission pipeline from the west to the east,China has ushered in a new peak period for pipeline construction.This article reviewed and summarized the technical development of the oil and gas pipelines crossing rivers and also different construction methods concerned.It compared the advantages and disadvantages of the technologies between buried trenches,directional drilling,tunneling,etc.,at the same time concrete examples were cited.This paper also gave an introduction to the proper application and the required condition of each specific method and relevant attention which is to be drawn during construction.It can be served as a good reference for future river-crossing designs and construction of petroleum and natural gas pipelines.
