摘要
油气井中产生的高温高压CO2/O2环境会对钢材产生严重的腐蚀。综述了高温高压CO2/O2腐蚀的机理,介绍了影响CO2/O2腐蚀的主要影响因素及作用特点。
Severe corrosion was common phenomenon for oil pipe used in the oil and gas well with high temperature and high pressure CO2 and O2. The corrosion mechanism was reviewed as well as the effects of essential factors including pressures of O2 and CO2, temperature, pH and flow rate.
