Abstract:
This article studied the recovery factor of binary compound flooding using surface-active polymer as pre-slug respectively based on the homogeneous sand paced pipe model and on the two dimensional positive rhythm inhomogeneous physical models. According to experiment on homogeneous model, while pre-slug is 0.2PV, the recovery ratio of binary compound flooding using surface-active polymer as pre-slug increases 4.03%, additionally, the pressure increases because of emulsification of surface-active polymer, so surface-active polymer has high oil sweep efficiency; According to experiment on inhomogeneous physical models, because of strong ability of emulsification, plugging and profile control, the recovery ratio of binary compound flooding using surface-active polymer as pre-slug increases 4.82%.
