X65钢在CO2饱和油田水中的电化学行为和腐蚀机理
Electrochemical Behavior and Corrosion Mechanism of X65 Steel in CO2-saturated Oilfield Water
摘 要
利用热力学计算方法推断X65钢在CO2饱和模拟油田水中的腐蚀反应阳极机制.结果显示X65钢在CO2饱和模拟油田水中的腐蚀包含两种阳极反应,即Fe接受电子转变为Fe2+和Fe与HCO-3反应形成FeCO3.实验条件下Fe与水作用生成Fe(OH)2的反应的平衡电位高于自腐蚀电位,因此难以进行.通过电化学阻抗谱测试进一步证实了热力学计算的结果.

Abstract
Mechanism of anodic reaction of X65 steel in CO2-saturated oilfield water was inferred from thermodynamic calculation.It was found that X65 steel was corroded through both reactions Fe→Fe2++2e and Fe+HCO-3→FeCO3+H++2e.Under the experimental condition,the reaction Fe+2H2O→Fe(OH)2+2H++2e could not take place because its equilibrium electrode potential was higher than the free corrosion potential of the steel.EIS results were consistent with the result of thermodynamic calculation.
