The former studies have largely covered the factors affecting foam stability rather than the effect of foam stability on foam flooding. The authors present the results of a laboratory study of polymer enhanced foam flooding, including different gas/liquid ratio, injection time, and foam drainage half time t(1/2), and, additionally, the foaming stability comparison of common and enhanced foam under high pressure. The results showed that polymer can highly strength foam stability, the foam which t(1/2) was 24 min with the gas\liquid ratio of 2: 1 at the moment of water cut reached 95% received the most oil incremental volume.
