Abstract: Under special conditions,oils in corrosion environment have some inhibitive effect on CO2 corrosion behavior of gathering pipelines.Whether or not the oil wetting and corrosion product film are considered becomes a great difference in existing rate prediction models of sweet corrosion.The progress of CO2 corrosion rate prediction models including empirical model,semi-empirical model,mechanistic model and artificial neural network model considering the effects of oil in recent years is introduced in detail,the present problems and further research directions are also discussed.
