摘　　要：大庆油田中的油水井套管因为体积较大,调电压常会发生火花喷射的情况,所以需要为其进行阴极的保护。为此特地设计了油水井套管防蚀阴极保护在线远程监控系统,通过在线和远程监控装置来对油水井套管进行电流阴极保护。与远程监控中心的阴极保护过程实施监控的方式相结合,这一系统的运行效率高、体积小、成本低、运行方便等特点更加突出。目前大庆油田已经有30多个京族应用,让油井套管发生腐蚀的情况有了大幅度降低,保证了油田发展的需求。Because of the large volume of oil well casing in daqing oilfield, spark injection often occurs in voltage regulation, so cathodic protection is needed. For this reason, the on-line remote monitoring system of casing corrosion prevention cathodic protection is specially designed. Combined with the way of monitoring the cathodic protection process of the remote monitoring center, this system features high efficiency, small volume, low cost and convenient operation. At present, daqing oil field has been used by more than 30 Beijing people, which greatly reduces the casing corrosion and ensures the development of oil field.
