摘要
模拟羊三木油田油藏地质条件，开展了碱－聚合物体系驱油机理室内研究。通过与单一碱、聚合物体系的分别对比，对碱－聚合物复合体系的油水界面性质、碱耗、聚合物滞留量、体系的稳定性，以及碱、聚合物、碱－聚合物体系的驱油效果和不同注入方式进行了室内实验研究。
The results in laboratory about caustic polymer system flooding mechanism in reservoir geology physics condition of Yangsanmu Area Dagang Oilfidld are reported. The interfacial properities of oilwater, caustic consumption ,polymer retention and stability of caustic polymer system, as well as coreflooding test of caustic,polymer, caustic polymer are studied respectively. The variety of injection manners of caustic polymer system is also discussed. It reveals the mechanism of enhancing oil recovery by caustic polymer system base on comparing and analyzing of studied results.
