摘要:主要结合墨西哥的一条使用了该评价技术的多相流管线实例,介绍油、气、水混输的多相流管线内腐蚀直接评价(ICDA)技术,重点介绍了多相流管线ICDA的间接检测阶段。采用多相流瞬态模拟软件(OLGA)结合风险分析技术绘制出基于风险分析的内腐蚀敏感度剖面图,从而确定出管线最容易发生腐蚀的高风险临界位置。

Abstract:Based on a multiphase flow pipeline which used this technique in Mexico,the internal corrosion direct assessment for oil, gas and water mix transportation pipeline,especially the indirect inspection phase,was introduced.Using multiphase flow transient state simulation software (OLGA) and risk analysis technology,a riskbased internal corrosion susceptibility profile will be created.Therefore,critical sites with high risks,and prone to corrode,are confirmed.
Key words:multiphase flow modeling; internal corrosion direct assessment (ICDA); risk analysis; corrosion susceptibility profile |
