摘要:

研究了P110SS钢在含低硫化氢油气井下腐蚀规律及特征。通过高温高压反应釜模拟超深井的腐蚀工况，对P110SS钢在不同温度、H₂S、CO₂分压条件下进行浸泡实验，通过腐蚀失重计算其腐蚀速率，辅以SEM、EDS和XRD等手段对腐蚀产物的形貌和成分进行表征。结果表明，H₂S、CO₂分压增大均会导致P110SS的腐蚀速率增大；然而温度升高却降低其腐蚀速率。分析腐蚀产物可见，H₂S、CO₂浓度和温度的变化均会导致腐蚀产物成分和结构发生转变。说明在高温高压条件下，H₂S腐蚀起主导作用，Fe₇S₈腐蚀产物对基体的保护作用较差，腐蚀速率高；低H₂S分压下，CO₂腐蚀起主导作用，腐蚀速率的大小取决于腐蚀产物膜的致密性；相比于CO₂，温度对腐蚀速率的影响更显著。

Abstract：

The corrosion condition of ultra-deep oil- and gas-wells is simulated via a high-temperature and high-pressure reaction kettle that can adjust the temperature, H₂S- and CO₂- partial pressure of the artificial formation waters. The corrosion characteristics of P110SS steel in the artificial formation water by varying temperature, and H₂S- and CO₂-partial pressure, was assessed by means of immersion test, SEM, EDS and XRD. The results show that the corrosion rate of P110SS increased with the increase of H₂S and CO₂ partial pressure, but decreased with the increase of temperature. By analyzing the corrosion products, it is found that the change of H₂S-, CO₂- partial pressure and temperature will lead to the change of composition and structure of corrosion products. This shows that under the condition of high temperature and high pressure, the corrosion of H₂S is dominant, the corrosion product of Fe₇S₈ has poor protectiveness and thus the steel presents high corrosion rate, and the corrosion of CO₂ is dominant under the condition of low H₂S partial pressure, the corrosion rate depends on the compactness of the corrosion product film. However, the effect of temperature on the corrosion rate is more significant than that of CO₂.

Key words： P110SS casing steel low H₂S partial pressure corrosion rate composition of corrosion product film
