Abstract: Slim tube displacement test results indicate that CO2 miscible flooding in tight sandstone reservoir in northern Shaanxi cannot be implemented. In order to define the contribution and the influence rule of supercritical CO2 properties on displacement characteristics in the condition of immiscible flooding,supercritical and non-supercritical CO2 oil displacement experiments were conducted. The results show that supercritical state of CO2 has a positive influence on oil displacement,and the small change of pressure near by the supercritical pressure point from non-supercritical to supercritical can bring a great difference of driving characteristics. After 0.5 PV cumulative injections,the effect of supercritical CO2 flooding is significantly better than that of non-supercritical flooding. The advantage stage for supercritical flooding is mainly when the cumulative CO2 injections reach between 0.5 PV and 1.5 PV,the recovery is about 10% higher than that of non-supercritical flooding under the same conditions. The oil change ratio of supercritical flooding and non-supercritical flooding occurs peak nearly at the same injection time (about 1 PV), but the former is significantly higher than the latter. In short,whether in the injection performance,or in the oil displacement efficiency and oil change ratio,supercritical flooding is better than non-supercritical flooding.

Key words: organic pore, surface porosity, shale porosity, kerogen, shale oil, resource assessment
