Study on Physical Simulation Experiments of Different Chemical Displacement Systems

Abstract:

In the reservoir condition of Liaohe oil field, the indoor physical simulation experiments of polymer / surfactant binary combination flooding and polymer / surfactant / alkali (ASP) flooding in the artificial cores have been conducted. The results show that enhanced oil recovery of polymer flooding is about 24.4%, by utilizing experiment project that polymer molecular weight is 19 million, main slug concentration is 1500mg/L. Binary flooding system that molecular weight of polymer is 19 million, main slug concentration is 1500mg/L, 0.3% surfactant YR has improved the oil recovery by 30.1%. The ASP flooding system (19 million 1500mg/L polymer +0.3% surfactant SS+ 1.2%Na₂CO₃) has improved the oil recovery by 28.4%. It can be seen that the binary flooding system is best.
