摘　　要：大型输油站(库)采取区域性阴极保护防腐蚀技术,具有投资少、见效快和安全可靠等特点,因而在防腐蚀设计中越来越多地被采纳.大庆油田储运销售分公司采用深井阳极对站内储油罐和地沟、埋地管线实施区域性阴极保护后,监测各测试点的保护电位在-0.85～1.4V范围,达到了有效保护的目的.实践证明,站(库)内的杂散电流干扰微弱,可不予考虑.同时指出,加强腐蚀控制管理对设备安全运行具有重要意义.As the cost efiective regional cathodic protection technology for large oil terminals is low in investment and reliable in operation, it is increasingly applied in anti - corrosion engineering. After the deep - well anode station was installed by Storage and Sales Company of Daqing Oil Field Co. , Ltd to protect the oil storage tanks, trenches and buried pipelines, the protection voltage of each monitoring point was -0.85 ~ 1.4 V which is the indication of good protection. The weak stray current in the terminal could be neglected. In addition, strengthening corrosion control management also plays an important role for the safe operation of equipment.
