石油天然气工业随着社会经济的发展也快速成长起来,油气的运输通常都是通过管道进行,越来越多的需求要求石油天然气管道建设向长距离发展。因此长运输管道的泄漏和检测问题成为了关注的热点,本文探讨了石油天然气长运输管道泄漏的原因,并对目前应用的检测和定位技术进行了简单的介绍,以期为我国石油天然气长运输管道的建设与泄漏检测技术提供参考。 As the socio-economic development of oil and gas industry has also rapidly grown up, the transportation of oil and gas are usually carried out through pipelines, more and more demand for the long-term development of oil and gas pipeline construction. Therefore, long-distance pipeline leakage and detection problems have become the focus of attention. This paper explores the reasons for the leakage of long oil and gas pipelines, and introduces the current detection and location technology for a brief introduction to China’s long-standing oil and gas pipelines Construction and leak detection technology to provide a reference.
