| Abstract: | The mechanism of fluid flow and physicochemical phenomena in thermal-surfactant combination flooding process were studied. Taking account of emulsion formation and its effect, a three dimension, three phase, multi-component combination flooding mathematical model was developed. Using the developed software to study the mechanism of combination flooding, the percolation mechanism and various factors which dominate the effect of combination flooding were investigated. The results indicate that the surfactant character and concentration have effects on the combination flooding. The improved mobility ratio and the adjusted cut plane by the emulsion enhanced the heavy crude recovery efficiency. |
