长输天然气管道泄漏检测技术探讨及选择参考

Discussion and selection of leak detection technology for long-distance Natural Gas Pipeline

我国已经形成了由西气东输一线和二线,陕京线、川气东送为骨架的横跨东西、纵贯南北、连通海外的全国性供气网络,但在建设规模日益增长的同时,管道泄漏带来的安全隐患逐渐成为大家关注的问题。目前国内外的泄漏检测技术有很多,但能够实际用于长输天然气管道实践的技术不是很多,本文重点是从实用角度出发,结合我国天然气管道现状对长输天然气管道的泄漏检测技术的性能和选择进行探讨,为长输天然气管道管理者选择检测方法提供参考依据。

China has already formed a nationwide gas supply network spanning the east-west,north-south and overseas,with the first and second lines of the west-east gas pipeline,the Shanxi-beijing line and the sichuan-east gas pipeline serving as the framework.However,while the construction scale is growing day by day,the safety hidden danger brought by the pipeline leakage has gradually become the problem that everyone pays attention to.At present,there are many leak detection technologies at home and abroad,but there are not many technologies that can be used in the practice of long-distance natural gas pipeline,based on the present situation of natural gas pipeline in China,the performance and selection of leak detection technology for long-distance natural gas pipeline are discussed.
