| Abstract: | 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. |
