研究了9 MPa和不同温度（50 ℃、65 ℃和80 ℃）下30%原油（v/v）对J55碳钢在超临界CO2/盐水中腐蚀速率、形貌、化学成分和腐蚀深度分布的影响。原油对腐蚀有明显的抑制作用，可以改变腐蚀形态和腐蚀类型。在腐蚀深度分布分析中，暴露表面积占42.14%，该值远大于其他方法。腐蚀深度分布符合高斯分布，分布参数可以反映平均腐蚀速率和腐蚀形貌。
The influence of 30% crude oil (v/v) on the following corrosion properties of J55 carbon steel in supercritical CO2/brine was investigated at 9 MPa and different temperatures (50 °C, 65 °C, and 80 °C): corrosion rate, morphology, chemical composition, and corrosion depth distribution. Crude oil had an evident inhibitory effect on corrosion and could change morphology and corrosion type. In the analysis of corrosion depth distribution, 42.14% of the exposed surface area was occupied, and this value was much larger than that of other methods. Corrosion depth distribution conformed to Gauss distribution, and the distribution parameters could reflect the average corrosion rate and corrosion morphology.
