摘　　要：针对CO2 强化采油的具体条件 ,对高CO2 分压、高矿化度条件下CO2 腐蚀的规律进行了探索 ,对缓蚀剂IMC- 871-G在各种温度、压力条件下的使用效果进行了实验 .在CO2 强化采油矿场实验中综合运用了各种CO2The CO 2-induced corrosion behavior of piping steels in high salinity sewage under high CO 2 partial pressure was studied.The effectiveness of corrosion inhibitor IMC-871-G at different temperature and pressure was also examined.A number of corrosion control methods were adopted in field tests of CO 2 aided EOR process,and the results indicated that those methods were efficient.
