油田埋地金属管道腐蚀及防腐措施

Corrosion and Anti-corrosion Measures of Buried Metal Pipelines in Oil Fields

在社会不断进步,经济水平不断提高的时代背景下,石油的用量越来越大,对石油的运输作业也有了更高的要求。用于石油运输的管道主要是由钢材制造而成,这些钢材极易被原油中像硫化物这样的具有腐蚀性的化学物质所腐蚀,长时间的腐蚀反应必然会损坏管道,造成石油泄漏,这将极大地降低石油产业的经济效益。该文章针对油田埋地金属管道存在的腐蚀问题提出具体的解决方法。

With the continuous progress of society and the continuous improvement of economic level,the consumption of oil is increasing,and there are higher requirements for oil transportation.Pipelines used for oil transportation are mainly made of steel,which is easily corroded by corrosive chemicals such as sulfide in crude oil.Long term corrosion reaction will inevitably damage the pipeline and cause oil leakage,which will greatly reduce the economic benefits of the oil industry.This paper puts forward specific solutions to the corrosion problems of buried metal pipelines in oil fields.
