国外沙漠地区油气田集输管道标志桩优化设计

Optimization Design of Marking Piles for Gathering and Transportation Pipelines in Oil Gas Fields of Desert Areas Abroad

标志桩是油气管道的重要附属设施,它不仅标明了管道设施的存在并警告公众和操作者其存在风险性,同时其包含应急联系等信息供公众使用。在中东及非洲等海外油气田项目中,标志桩也广泛使用。由于此类地区沙漠地形比较常见,而沙漠中油气管道标志常因环境而褪色失去标识作用,从而带来运营隐患。为解决因风沙侵蚀导致桩体及字体褪色而使标识作用失效的问题,以非洲某油气田项目为例,提出了结合现场情况经过改进的管道标志桩的设计、制作、安装方法。经同其他桩体的经济对比,表明该设计方案经济性及可实施性有明显优势,对海外油气田项目设计施工提供了有益的参考。

Marker piles are important auxiliary facilities of oil and gas pipelines.They not only indicate the existence of pipeline facilities and warn the public and operators of their risks,but also contain emergency contact information for public use.Marker piles are also widely used in overseas oil and gas field projects in the Middle East and Africa.As desert terrain is common in such areas,the marks of oil and gas pipelines in the desert often fade and lose their marking function due to the environment,thus bringing hidden dangers to operation.In order to solve the problem of the ineffectiveness of the logo due to the fading of pile and font caused by sand erosion,taking an oil-gas field project in Africa as an example,an improved design,fabrication and installation method of marking piles is proposed.Through economic comparison with other marker types,it is indicated that the modified design has ob-vious advantages in economic and fabrication feasibility,which provides a beneficial reference for the design and construction of overseas oil-gas field projects.
