Abstract In order to study the corrosion mechanism of Cr5 and Cr7(wt.%) steel under CO2-EOR high temperature and high pressure service condition,the corrosion behavior was simulated by using high temperature and high pressure reactor,and the corrosion rate was measured by weight loss method to compare the corrosion resistance of two test steels. Corrosion products were observed and analyzed by SEM,EDS,XRD and XPS. The corrosion mechanism of test steels under CO2 corrosion conditions was discussed,and an intuitive corrosion mechanism model during the entire corrosion process was constructed. The research results show that the corrosion rate of Cr5 steel is 0.734 75 mm/a,and that of Cr7 steel is 0.217 32 mm/a. Corrosion products are composed of FeCO3 crystals in the outer layer and amorphous FeCO3and Cr(OH)3 in the inner layer. In the initial stage of corrosion,the product film is formed by in-situ generation and gradually deposited after anodic dissolution. After the product completely covers the substrate,the diffusion and deposition of ions at the interface becomes the main way for product film growth.
