Abstract In the simulating the environment of CO2 corrosion in oilfield, XRD and SEM techniques were adopted to study the formation and development of CO2 corrosion product film on X65 steel. The results demonstrated that the corrosion scales are three layers in the cross-section. Structural characteristics and formation mechanism of the film were discussed respectively.

Key words: CO2 corrosion corrosion product film X65 steel
