系统地总结了原油对CO2腐蚀过程的影响及其相应CO2腐蚀速率预测研究的进展情况，介绍了研究原油对CO2腐蚀过程影响方法，提出了研究该过程可能应注意的问题。在一定条件下，原油对腐蚀过程有一定的缓蚀作用。是否考虑原油润湿性和腐蚀产物膜，已成为不同CO2腐蚀预测模型主要的两大差别之一。对原油润湿性的处理方式及其影响因子能在很大程度上影响腐蚀预测的结果。研究原油的特性，认识它对腐蚀过程的影响规律，对研究、开发适宜的CO2腐蚀预测模型大有裨益；利用其可能的缓蚀作用，可节约设备成本投资和操作运转费用，有很大的现实意义。
This paper summarizes systematically the recent progresses in corrosion influences and rate prediction of sweet corrosion affected by crude oils, introducing the methods of studying corrosion process of sweet corrosion, and bringing forward the issues that may be paid special attention to while studying the influence of crude oils. However, crude oils usually demonstrate some inhibition in specific conditions. Corrosion product film and oil wetting are two great differences in existent rate prediction model in sweet corrosion. However, the approaches and manners to dispose crude oils will affect the prediction results no doubt. It is remarkably beneficial to study and develop an appropriate prediction model if the properties and laws toward sweet corrosion of crude oils are been studied thoroughly. And there is a realistic meaning in saving investment and operational costs while utilizing the possible inhibition of crude oils.
