Abstract

Effect of temperature on the electrochemical impedance spectroscopy for P110 steel at anodic polarized potential was investigated in simulated CO 2 saturated oil produced water. The results demonstrated that in the range from room temperature to 90 ℃, there was a critical temperature , below which a three time constant impedance spectrum was observed and above which a two time constant spectrum was shown. A reasonable explanation was given to this phenomenon in an effort to elucidate the mechanism of anodic dissolution and characteristics of CO 2 corrosion.
