In view of the internal corrosion problems of X80-X120 high-grade pipeline steels in the application of oil and gas pipeline engineering in China,the corrosion mechanism and the research progress at home and abroad were summarized for high-grade pipeline steels in single CO2 alone,single H2S alone,and CO2/H2S coexistence environment.The deficiencies of current domestic research on the internal corrosion and chemical protection of high-grade oil and gas pipeline steels were pointed out and the corresponding suggestions were also given.
