摘　　要：辽河油田特石热油管线担负着重要的输送任务,防腐是管道保护的主要手段。迄今为止,对埋地管道加阴极保护是最有效的防腐蚀措施。评定和控制阴极保护的水平,仍以电位测量为主。使用试片可以更方便地测量电位,在试片上进行电化学极化测量或电位衰减测量,求得阴极保护下管道金属的腐蚀速率和保护度,对管道阴极保护有效地进行实时监测和控制。Liaohe Oilfield TESHI pipeline for Thermal oil undertake a significant transportation task,to prevent corrosion is the primary means of protection for the pipeline.Cathode protection of buried pipelines is one of the best corrosion-proof methods.So far,the main way of evaluating and measuring cathode protection is potential measurement.Using specimens are able to be more convenient to measure the potential,the corrosion rate and protection level under cathode protection were obtained by the methods of polarization and potential decline measurement,which is beneficial to monitor and control real-time cathode protection.

关 键 词：埋地管道 阴极保护 电位测量 电阻率
