埋地天然气管道杂散电流检测与评价

Detection and Evaluation of Stray Current in Buried Natural Gas Pipeline

文中研究了涪陵页岩气田某埋地管道杂散电流干扰,进行了土壤表面电位梯度测试、管地电位测试、交流电压测试、土壤电阻率测试、SCM杂散电流重点检测。结合相关标准对检测结果进行评价发现:该埋地天然气管道全线直流和交流干扰程度均为弱,不需要采取直流或交流干扰防护措施。

This paper studied stray current interference of a buried pipeline in the Fuling shale gas field,the soil surface potential gradient test,the pipeline-ground potential test,the AC voltage test,soil resistivity test and the SCM key test were carried out.Evaluation of the test results in combination with relevant standards find that the entire line of the buried natural gas pipeline has weak DC and AC interference levels,and the pipeline does not need to take DC or AC interference protection measures.
