首先介绍了常用的腐蚀监测技术，然后论述了哈法亚油田三期原油中央处理厂（CPF3）所使用的电阻探针、腐蚀挂片、超声波定点测厚三种腐蚀监测技术，并根据处理装置的工艺特征、腐蚀状况及使用经验探讨了腐蚀监测点的选用原则与分布，最后介绍了哈法亚油田CPF3的腐蚀监测网络的构建，该网络使多种腐蚀监测技术在哈法亚油田得以成功应用。

Firstly, the common corrosion monitoring technology is introduced. Then, three kinds of corrosion monitoring techniques, resistance probe, corrosion coupon and ultrasonic spot wall thickness monitor system, used in the third stage of central processing factory (CPF3) for crude oil in Halfaya oilfield are expounded. According to the process characteristics, corrosion conditions and service experience, the selection principle and distribution of corrosion monitoring points are discussed. Finally, the construction of CPF3 corrosion monitoring network of Halfaya oilfield is introduced, this network successfully applied various corrosion monitoring technologies to Halfaya oilfield.
