摘要
采用断电法、极化探头法和试片断电法对塔河油田不同管道的阴极保护电位进行测量,发现了日常管理中测试方法的误差,提出针对不同阴极保护情况的管道应采用不同的测试方法来消除IR降和干扰电流的影响。
Using methods of current interruption, polarization probe method and external CP coupons, the cathodic protection potentials of different pipelines in Tahe oilfield were measured. It is pointed out that in different cathodic protection systems, different testing methods should be used to eliminate the IR drop and interference current influence.
