摘要
在模拟油田CO2/H2S共存的腐蚀环境中,研究了温度、CO2分压、H2S分压对N80、P110两种油管钢动态腐蚀行为的影响。结果表明,在实验参数范围内,随着温度、CO2分压、H2S分压的变化,两种材质的动态腐蚀速率都呈现了先增大后减小的变化趋势,且P110钢的腐蚀速率大于N80钢的腐蚀速率。
It was studied the effects of temperature,partial pressure of CO2 H2S on corrosion behaviors of tubing steels,which included N80 and P110,in simulated CO2/H2S corrosion environment of oilfield.The results show that the corrosion rates increase at first and then decrease with increasing of temperature,CO2 partial pressure,and H2S partial pressure.And the corrosion rates of steel P110 are always higher than that of steel N80.
