| Abstract: | Low permeability reservoirs are widely distributed in China, and these kinds of reservoirs generally have the characteristics of low porosity, low permeability and low recovery. According to development characteristics of low permeability reservoirs, the merits and demerits of different kinds of enhancing oil recovery methods were analyzed for improving the development effects in low permeability reservoirs. Foam flooding is one better way to improve the development effects of low permeability reservoirs, which can increase sweeping efficiency and oil displacement efficiency. Finally, the orthogonal experiment design was adopted, and 9 cases were designed in L9(34) orthogonal table, so foam flooding to enhance oil recovery was studied in one low permeability reservoirs. In this research the effects of injection mode, slug size, surfactant concentration and gas-liquid ratio on the oil recovery were analyzed, and the optimal development program of foam flooding was optimized. Comparing with water flooding program, the optimed foam flooding could enchance oil recovery by 7.32%. |
