Abstract
Based on Nesic mechanism of CO2 corrosion,considering mass transfer rate in fluid boundary layer and corrosion product scale an experimental method for determination of corrosion product scale factors and a new prediction model of CO2 corrosion rate is proposed.The technique of analyzing and determining corrosion product scale factors according to test results at high temperature and high pressure is also presented.Effect of mineral degree of solution on corrosion rate is also discussed.The proposed model is consistent with the test results.
