Abstract Calcium and magnesium ions are major constituent species in produced brines associated with oil and gas production. Existing literature is often contradictory and unclear as to whether the presence of such ions accelerates or retards general corrosion. Furthermore, their influence on initiation and propagation of localized corrosion remains ambiguous. This review presents state-of-the-art knowledge concerning how Ca2+ and Mg2+ influence the CO2 corrosion mechanism. In addition, a best way forward is proposed in order to bridge the existing literature gaps in studying the influence of these alkaline earth cations on CO2 corrosion.

钙和镁离子对油气生产系统中碳钢 CO2 腐蚀的影响 - 综述

摘要 钙和镁离子是与石油和天然气生产相关的生产盐水中的主要成分。现有文献对于此类离子的存在是否会加速或延缓全面腐蚀通常是矛盾和不清楚的。此外，它们对局部腐蚀的发生和传播的影响仍然不明确。本综述介绍了有关 Ca2+ 和 Mg2+ 如何影响 CO2 腐蚀机制的最新知识。此外，为了弥合现有文献在研究这些碱土金属阳离子对 CO2 腐蚀的影响方面存在的空白，提出了一种最佳方法。
