摘　　要：特低渗油田目前以注水开发为主，开发难度大、采收率低．以URH油田为研究对象，通过泡沫辅助气水交替驱机理研究和室内物模实验验证了在特低渗透油藏用泡沫辅助气水交替驱来提高采收率的可行性。，实验结果表明，泡沫辅助气水交替驱比水驱提高采收率10．1％，说明泡沫辅助气水交替驱是一项具有适用价值的提高采收率技术．、At present, low-permeability oil tields are mainly water development, there is a low recovery, development problems and poor results. In this paper, URH field as the research object, through the foam-assisted water alternating gas- drive mechanism of the physieal model and an indoor experiment to test the ultra-low permeability reservoir foam-assisted water ahernating gas EOR feasibility. Experimental results show that the bubble-assisted water alternating gas than water flooding EOR 10.1%, indicating a bubble-assisted water alternating gas drive is the one with the value of the enhanced oil recovery technology.
