钙和镁离子是与油气生产相关的生产盐水中的主要成分。现有的文献往往是矛盾的，不清楚这些离子的存在是加速还是延缓一般的腐蚀。此外，它们对局部腐蚀的发生和扩展的影响仍然不清楚。这篇综述介绍了关于Ca2+和Mg2+如何影响co2腐蚀机制的最新知识。此外，为了弥补这些碱土阳离子对co2腐蚀影响的现有文献空白，提出了最好的前进方向。
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 CO2corrosion 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 CO2corrosion.
