阳极地床位置在油气长输管道中的优化设计

Optimization Design of Anode Ground bed for Oil and Gas Transmission Pipeline

针对国内土地资源日益紧张,油气长输管道阳极地床选址问题日益突出的现状,本文主要从阳极地床的类型、选址原则及阳极地床的电压场分布等方面进行分析。在保证阴极保护效果的前提下,通过阳极地床电压场强度与保护电流、土壤电阻率及与被保护管道位置的相互关系,理论计算阳极地床与被保护管道的距离,从而优化选择阳极地床位置。

According to the domestic land resources increasing tense, the location problem for anode bed of oil and gas transmission pipeline increasing prominent. In this paper, the types of anode ground bed, the location principle and the voltage field distribution of the anode ground bed are analyzed. Under the premise of ensuring the effect of cathodic protection, Analyze the relationship between the voltage field intensity and the protection current, the soil resistivity and the position of the pipeline, calculate the distance between the anode ground bed and he protected pipeline, to optimize the best anode ground bed position.
