| 摘 要： | 通过长岩心驱替实验,比较了CO2与N2的驱油效果,进行了不同注入速度下的CO2驱油效率,模拟了不同气水比条件下的水-CO2交替注入情况。研究结果表明：CO2驱驱油效果优于N2;较低的注入速度下,CO2驱油效率较高;水气比较低时,CO2-水气交替注入效果较高。

| Abstract: | Displacement effects of CO2 and N2 were compared through long core flooding experiments.Simultaneously,CO2 flooding and water-gas alternative injection were investigated.The results show that CO2 is superior to N2 in gas flooding.Low flooding rate contributes to higher displacement efficiency.Low gas-water ratio obtains better oil recovery. |

| Keywords: | Low permeability CO2 flooding Injection rate water-gas alternative ratio |
