| 摘 要： | 从氮气的物理性质出发,研究氮气、水交替非混相驱油机理;然后从实验出发,对氮气、水交替非混相驱油驱替机理、驱替效率、饱和度分布、压力分布以及油田含水率变化过程等问题进行了实验研究;结果表明,氮气、水交注驱油效率明显高于纯水驱驱油效率,不同的驱替方式对最终驱油效率影响很大。

| Abstract: | Based on some physical properties of nitrogen, nitrogen alternating water immiscible displacement mechanism was studied. Through experiments in laboratory, nitrogen alternating water miscible flooding displacement mechanism, displacement efficiency, saturation distribution, pressure distribution, oil field water content change and so on were researched. The results show that displacement efficiency by nitrogen alternating water injection is significantly higher than that of single water flooding , and different displacement ways have great influence on displacement efficiency. |
