| 摘 要： | 工业和人类生活过程中排放的温室气体CO2已使全球气候变暖,人类生存的地球环境日趋恶化.世界大部分油田采用水驱开发,将CO2注入水驱开发油田不仅能减轻CO2的排放量,而且可以提高水驱后油藏的原油采收率.通过岩心驱替实验,分析了水驱后油藏在不同地层压力条件下CO2的驱油特征,并对不同地层压力下CO2的埋存量进行了计算.实验结果表明,CO2驱可以很好地提高原油采收率,约15%,地层压力越高,采出率越高,同时证明了水驱后油藏是CO2埋存的理想场所.

| Abstract: | Water-flooding is used in most oil fields in the world. The CO2 -injection to the water -flooded oil fields will not only reduce the CO2 emission, but also enhance the oil recovery. Through the core displacement experiment, this paper analyzes the CO2 displacement characteristics in water -flooded reservoir under different formation pressures and calculates the CO2 storage capacity. The results show that the CO2 injection can enhance the oil recovery by about 15% , with higher formation pressure. It is conc... |
