Hydrogen Permeation Behavior of 95S3Cr Casing with Wet H2S Environment
This paper discusses the amount of hydrogen permeation and corrosion rate of 95S3Cr casing in different time, and analyzes its morphology before and after corrosion. We conclude that hydrogen permeation increases with increases of corrosion time, and increasing speed is faster in the initial stages then slower. Corrosion rate is quickly dropped at the beginning and then gradually increased. Corrosion products are loose structure. Because of hydrogen permeate into the material, the cracks create. It accelerates the corrosion.
