摘　　要：埋地油气混输管道的腐蚀都是油气输送工作中十分棘手的问题。埋地管道具有外环境复杂的特点,且管道内部需要输送高温高压的多相流体,所以发生腐蚀的可能性较大。本文对埋地油气混输管道的腐蚀机理进行分析,同时提出相应的防护策略,以供参考。The corrosion of buried oil and gas pipelines is a very difficult problem in oil and gas transportation. Buried pipeline has the characteristics of complex external environment, and the pipeline needs to transport high temperature and high pressure multiphase fluid, so the possibility of corrosion is large. This paper analyzes the corrosion mechanism of buried oil and gas pipelines, and puts forward corresponding protection strategies for reference.
