摘　　要：为了促进油气管道站场区域性阴极保护实施达到预期效果,文中采用综合归纳总结的方式分析了区域阴极保护设计应用的技术特点,介绍了区域阴极保护技术的设计原则和计算内容,提出了区域阴极保护技术实施中需要关注的问题和技术对策,对于站场区域阴极保护技术的开展具有一定的借鉴作用。In order to gear up achieve of regional cathodic protection in the oil-gas pipeline process station,in this paper,an integrated deductive method was employed to analyze technical feature of regional cathodic protection for pipelines. The design philosophy and calculation details of regional cathodic protection technical were introduced. The questions and relevant technical countermeasures of regional cathodic protection were proposed. There is some reference value for development of regional cathodic protection technology.
