| Abstract: | This paper describes the status of long-distance pipelines.Five common methods for outside detecting of oil gas pipelines include pipeline current mapper（PCM） method,the direct-current voltage gradient（DCVG） method,the standard pipe / sub-ground voltage detection technology（P / S）,the current gradient detection technology（CGDT）,and the close interval potential method（CIPS）.The advantages and disadvantages of several main methods used in Sichuan Province are compared with each other so as to introduce the applicability.Finally,the development trend for the inspection technologies of oil and gas outside pipelines are introduced. |
