摘　　要：在含H2S气体的油气田开发中，H2S的腐蚀问题很严重，不仅腐蚀套管，而且对水泥石的腐蚀也很严重。在这些油田开发中，固井问题变得复杂，如果我们能研究清楚H2S对固井水泥石的腐蚀问题，那么就能更好的采取防治措施防止H2S对固井水泥石的腐蚀，更能防止对套管的腐蚀。本文分析了固井水泥石H2S腐蚀的腐蚀机理，以及影响因素，阐述了固井水泥石抗H2S腐蚀的机理、方法、水泥浆体系，耐H2S腐蚀水泥浆类型。In the oil field development of contain H2S,the H2S corrosion problem very serious, not only decay casing,and the corrosion of cement sheath also very serious. In these oil field development,well cementation becomes complicated,if we can study clear the H2S corrosion problem of the well cement sheath, so the prevented measures is better to adopt and prevent the H2S corrosion from well cement sheath, and even prevent the corrosion from casing. The paper analyzed the corrosion mechanisms and impact factors of HzS corrosion of well cement sheath,elaborated the anti-corrosion mechanism,method,cement slurry system of HzS corrosion of cement,the types of anti-corrosion cement slurry of H2S corrosion .
