油气井生产中的腐蚀与防护

The corrosion and protection of oil and gas well

在油气开采过程中,伴随高温高压以及高流速条件,金属腐蚀成为一种很普遍很严重现象。腐蚀会造成油、套管破裂,井口装置失灵,输气管线爆裂,站场设备锈蚀等。文中总结了腐蚀产生的危害,分析了腐蚀产生的原因,简要回顾了常用的防腐技术。

Metal corrodes has now become very common and grave phenomenon for the oil and gas well under heavy pressure and high flow rate of well temperature condition. Metal corrosion may cause oil and casing pipe breaking, wellhead equipment failure, being conveying gas pipeline blowout, the station equipment rustiness and so on. This paper summarizes the hazards of corrosion, analyses the corrosion causes, gives a brief review of the commonly used anti-corrosion technology.
