石油管道腐蚀原因及防腐

Corrosion Causes and Corrosion Prevention of Oil Pipeline

石油管道所处的环境特殊,因此非常容易出现腐蚀的情况,国内石油开发进入到了后期发展,在采出液中有硫化氢等带有腐蚀性的物质,加上高温以及高压等作用,让石油管道的内壁容易受到腐蚀,外部也容易受到微生物以及土壤电解质等方面的影响。而石油管道对经济发展承担着重要的作用,石油运输要想保持良好的效率,就需要石油管道保持在非常好的状态,对石油管道采取合理的防腐措施至关重要。因此,主要对石油管道出现腐蚀的一些原因展开分析,并在防腐方面提出一些建议,希望对石油行业发展有促进作用。

The environment of oil pipeline is special,so it is very easy to be corroded.In China,the oil development has entered into the later stage.There are corrosive substances such as hydrogen sulfide in the produced liquid,coupled with high temperature and high pressure,which make the inner wall of oil pipeline vulnerable to corrosion,and also vulnerable to microbial and soil electrolyte outside.。The oil pipeline plays an important role in economic development.If the oil transportation wants to maintain good efficiency,it needs to keep the oil pipeline in a very good state.It is very important to take reasonable anti-corrosion measures for the oil pipeline.This paper analyzes the causes of the corrosion of oil pipelines,and puts forward some suggestions on corrosion prevention,hoping to promote the development of the oil industry.
