| Abstract: | It is water injection pipe column for polyethylene pipe column of the Bohai oil field, nitriding anticorrosion tube. The recent discovery of the original well out of the nitrided tubing wall has more corrosion penetration holes. According to the oil field mining and experimental analysis, the corrosion causes are analyzed and explained, and put forward some instructive suggestions. |
