IUCRC: Corrosion in Multiphase Systems

生产系统的腐蚀是所有石油和天然气生产公司面临的主要问题。这对于未来墨西哥湾深水区的生产来说尤其如此。在这些环境中，干预和修复非常昂贵，而且预测多相系统腐蚀的最新技术几乎不存在。在俄亥俄大学多相系统腐蚀工业/大学合作研究中心的头五年里，该中心在了解多相流对腐蚀的影响方面取得了实质性进展。这些知识是在数据库的基础上发展起来的，数据库中有5万多个点，这些点是在不同倾角、不同输入比、不同压力和温度下不同管道流速下的油/水/气含率和速度剖面上生成的。特别是，该中心在启发腐蚀界关于夹带气泡对管壁的冲击和崩溃的影响方面发挥了重要作用。虽然均匀腐蚀或一般腐蚀现在已经有了一定的认识，但局部腐蚀仍需要进一步研究。本次更新提案的研究重点包括以下新项目领域：1)缓蚀研究；2)酸性体系中的腐蚀；3)湿气系统的腐蚀；4)丘陵地形；5)段塞和腐蚀跟踪。

ABSTRACTEEC-9817958 JEPSONCorrosion in production systems is a major problem for all oil and gas producing companies. This is especially true for future production in the deep waters of the Gulf of Mexico. Intervention and remediation is extremely expensive in these environments and the state-of-the-art for predicting corrosion in multiphase systems is almost non-existent. In its first five years the Industry/University Cooperative Research Center for Corrosion in Multiphase Systems at Ohio University has the center has made substantial progress towards understanding the effect of multiphase flow on corrosion. The knowledge has been developed based on a database of more than 50,000 points generated on oil/water/gas holdup and velocity profiles at various inclinations, input ratios and flow rates at different pressures and temperatures in pipes of different diameters. Particularly, the Center has been instrumental in enlightening the corrosion community about the effect of the impact and collapse of entrained gas bubbles on the pipe wall. While uniform or general corrosion is now reasonably understood, localized corrosion still needs to be investigated further. The research foci of this renewal proposal include the following new project areas:1) Corrosion Inhibition Studies; 2) Corrosion in Sour Systems; 3) Corrosion in Wet Gas Systems; 4) Hilly Terrain; and 5) Slug and Corrosion Tracking.
