摘要
渤海某油田油井为水聚分注管柱,管柱涉及渗氮防腐油管。近期发现原井起出的渗氮油管外壁存在较多腐蚀透的孔洞。本文针对油井现场工况和实验分析,对腐蚀穿孔原因进行分析说明,并提出一些指导性建议。
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.
