     supercritical carbon dioxide (scco2) microemulsion was formed by supercritical co2, ha sodium bis(2-ethylhexyl) sulfosuccinate (aot, surfactant) and c2h5oh (co-surfactant) under pressures higher than 8 mpa at 45°c. the fundamental characteristics of the scco2 microemulsion and the minimum miscibility pressure (mmp) with daqing oil were investigated with a high-pressure falling sphere viscometer, a high-pressure interfacial tension meter, a pvt cell and a slim tube test. the mechanism of the scco2 microemulsion for enhancing oil recovery is discussed. the results showed that the viscosity and density of the scco2 microemulsion were higher than those of the scco2 fluid at the same pressure and temperature. the results of interfacial tension and slim tube tests indicated that the mmp of the scco2 microemulsion and crude oil was lower than that of the scco2and crude oil at 45 °c. it is the combined action of viscosity, density and mmp which made the oil recovery efficiency of the scco2 microemulsion higher than that of the scco2 fluid
