摘　　要：对某油田 9个计量站的调查统计 ,平均每 3.5天就有一处发生腐蚀泄漏 ,其中以外腐蚀最为突出。查其原因 ,与当地土壤电阻率低、介质温度较高、防护层不完整以及存在杂散电流等因素有关。A corrosion leakage occurred almost every 3.5 days on average based upon the statistics of 9 metering stations in an oil field, in which the external corrosion was the most remarkable. The causes of corrosion were found to be the low soil resistance, higher temperature media, incomplete protection coatings and existence of stray current, etc. The application of impressed current cathodic protection could control the corrosion.
