某油气站场接地系统对区域阴极保护效果影响规律的计算分析及处理方法
Calculation and Analysis of the Influence of Grounding System on Regional Cathodic Protection Design in Oil & Gas Station and Treatment Method
摘 要
为了分析和提高油气站场中区域阴极保护系统与铜接地系统的兼容性，采用数值模拟方法计算了不同阳极形式下站场铜接地系统对区域阴极保护效果的影响，比较了不同处理方式的效果。结果表明：靠近埋地管道的铜接地会严重影响管道阴极保护效果；将这些靠近管道的接地局部绝缘能够提升阴极保护效果；将水平接地完全绝缘能进一步提升阴极保护效果；另外，采用负电性的锌作为接地材料是一种可选择的方案。

Abstract
To analyze and improve the compatibility of regional cathodic protection system and copper grounding system in oil/gas stations, numerical simulation was used to calculate the cathodic protection (CP) effect in different anodic forms, and the effects were compared in different treatment measures. The results showed that the copper grounding near buried pipeline was the main cause of cathodic protection incompatibility. Patial or entire isolation of horizontal grounding electrodes could improve the CP effectiveness. Moreover, using electronegative materials like zinc as grounding material was an alternative option.
