压气站区域性阴极保护技术

Regional cathodic protection technique for gas compressor station

  • 摘要: 压气站等油气站场的地下管网、电气仪表接地、设备基础等地下设施结构复杂,阴极保护参数随土壤特性、气候特性、阳极布置位置和汇流点位置等的不同而有较大变化,在不同地区,甚至同一地区的不同站场都会表现出很大的差异性。通过对乌兹别克斯坦已建多个压气站出现的区域阴保问题进行综合原因分析、电位分布测量、设备性能优化、阳极增补、汇流点和参比电极位置调整,使其各项指标达到标准,取得了满意的效果。在此基础上总结了区域性阴极保护的规律特点,可为压气站阴保系统的设计和施工提供参考。

     

    Abstract: The buried structures in gas compressor stations or other oil/gas stations/terminals, including pipes, groundings of electrical instruments and equipment foundations, are complicated. Parameters of cathodic protection system vary greatly with the change of soil property, climate condition, location of anodes and confluence points. Therefore, great differences exist in different regions, or even in different stations/terminals within the same region. For problems occurred in regional cathodic protection in multiple gas compressor stations in Uzbekistan, some measures are taken to ensure all indicators qualified, such as cause analysis, measurement of potential distribution, device performance optimization, anode supplementation, and adjustment of confluence points and reference electrode locations. Satisfactory results have been achieved. On this basis, the rules and features for regional cathodic protection are summarized, which can provide a reference for the design and construction of cathodic protection system in gas compressor stations.
