为了保护压气站埋地管道及工艺管网的运行安全，区域阴极保护技术得到广泛应用。由于压气站场内埋地管道错综复杂，存在相互干扰，导致阴极保护系统间不平衡问题的矛盾也越来越突出，严重影响了压气站场阴极保护系统的有效运行，存在安全隐患和资源浪费。本文通过对西部某压气站场的阴极保护系统有效性的检测评价，分析了电位和电流输出大小、埋地管道保护电位分布和极化情况以及土壤IR降大小等影响因素，找到了造成阴极保护系统间不平衡的原因，并提出了合理的整改建议被提出，为解决站场区域阴极保护系统间的不平衡问题提供参考。

In order to protect the safety operation of buried pipeline and processing pipe network at certain compressor station, regional cathodic protection technology is widely used. It is intricate pipelines and interference between the cathodic protection systems that leads to the contradiction of the imbalance problems which becomes more and more prominent. The effective operation is seriously affected between the cathodic protection systems, so there are troubles in safety and wasting of resources. In this article, the effectiveness of the cathodic protection system at the western certain compressor station is evaluated, influence factors are analyzed, such as the potential and current output size, distribution of protection potential the polarization situation of buried pipeline and soil IR drop size. The causes of the unbalance between cathodic protection system are found, reasonable recommendations are proposed, and the reference is provided for solving the station imbalance between the regional cathodic protection system.
