With the rapid development of petroleum and gas industry, the corrosion problem of oil gas tubing caused by acidic gas becomes increasingly prominent, especially the H2 S corrosion phenomenon is widespread, which affects the service life of pipe-lines of oil and gas exploitation and transportation as well as the refining processing equipment. This paper systematically summa-rized the mechanism, main influencing factors and protection methods of H2 S corrosion of oil gas tubing, and the effects of tempera-ture, H2 S partial pressure, PH, flow rate and concentration of Cl-, CO2 partial pressure as well as pipe materials on H2 S corrosion were also discussed. H2 S corrosion rate prediction model was established and analyzed. Protection methods against H2 S corrosion were reviewed as well. Finally, this paper briefly described the current research situation and development trend of H2 S corrosion.
