摘　　要：本文以天然气长输管道阴极保护系统为研究对象,以实际数据为载体,讨论研究了日常管道巡护过程中在阴极保护方面存在的管理问题,特别是在保护电位的确定、杂散电流、防腐层完好性判定等方面应注意的事项,避免以某一个数值做出错误的判定,为埋地天然气管道防腐保护及检测工作提供了实践案例,对管道安全运行具有十分重要的指导意义。This paper has taken the cathodic protection system of long-distance natural gas pipeline as the research object and the actual data as the carrier.This paper has discussed and studied the management problems in cathodic protection during routine pipeline patrol,especially the matters needing attention in the determination of protection potential,stray current and the judgment of the integrity of anticorrosion layer,etc.,avoided making a wrong judgment with a certain value provided a practical case for the anti-corrosion protection and detection of buried natural gas pipelines,which is of great significance to the safe operation of pipelines.
