阴极保护在复杂断块油田的应用

中原油田是一个多层系、多油藏类型的复杂断块油田，随着油田开发时间的延长，油田已进入开发中高含水期，产出水矿化度高，腐蚀性强，地面集输管线及设施的腐蚀日益加剧，既影响了生产，又污染了环境。本文通过对其主力产油区块之一的胡状油田进行现场腐蚀状况调查，分析造成腐蚀的原因，针对其主要影响因素实施阴极保护措施，达到了延缓腐蚀、减少穿孔的目的。

Application of Cathodic Protection in Complex Fault-block Oilfield

Zhongyuan oilfield,which is a complex fault block oilfield with crushed zone and complex reservoir,has entered into the middle late period as the waterflood developed.Some influence factors such as high salinitiesed underground water,strong corrosirity make the gathering pipeling and facilities get worse.According to on site investigation of corrosion condititon in Huzhuang oilfield that is one of the main poroduction area,the paper analysis the reason of corrosion.In fact,a protecting measure for corrosion control is made according to the key factor,whose purpose is to control corrosion and decrease doring.
