油田地下管道的电化学保护研究

The Electrochemical Protection Research of Underground Pipeline in the Oilfield

江苏油田有部分油井位于淮河入江的泄洪道内，由于泄洪道内油田地下管道所处的环境与陆上不同，造成比在陆上的腐蚀情况要严重。通过土壤腐蚀性和现场电化学保护研究，得到地下管道的保护电位和保护半径。

Some oil wells of Jiangsu Oilfield locate in the floodway of the Huai River into the Yangtze River. Because the difference of environments between in land and in floodway, the corrosion condition of underground pipeline in floodway is more serious than the pipeline in land. The protection potential and the protection radius of undergrotmd pipeline in the floodway are gained by the soil corrosion research and the electrochemical protection research in the floodway.
