| 摘 要： | 利比亚西部管道平行敷设两条不同管径的原油管道和天然气管道,通过对其阴极保护系统的预试运,发现管道的电位出现异常的波动,且波动幅度超过了允许范围,管道可能存在杂散电流的干扰。通过对管道正常运行下的IR降、全线保护电位以及同步电位和交流干扰进行测试分析,成功地解决了管道阳极接地电阻问题、无电地区的电源问题以及杂散电流干扰问题、使该管道阴极保护参数处于理想状态。

| Abstract: | Libyan Western Pipelines,consisted in two DN400 oil pipelines and a DN800 gas pipeline,are parallel-laid with two pigging stations, 16 valve controlling stations and 10 cathodic protection stations in the pipeline system. The commissioning of cathodic protection system shows that the fluctuation amplitude of pipeline potential is more than the allowable scope,possibly the stray current interference. Testing and analysis on the IR drop (in the case of normal operation of pipeline), whole pipeline protection potential, sync-potential and AC interference are made,which successfully solve several problems in anode grounding resistance of pipeline, power supply in power-free area and stray current interference. The cathodic protection technology makes the cathodic protection parameters of pipeline being in ideal state. |
