中文摘要	A mathematical model of viscous-elastic polymer flooding was developed to study enhanced oil recovery mechanisms and to forecast oil exploitation performance. The model simulates both the elasticity effect and the viscosity mobility control effect. Polymer elasticity can reduce residual oil saturation, while polymer viscosity will improve the mobility ratio between the oleic and aqueous phases, which will expand the volumetric sweep efficiency. The main process mechanisms include increasing the displacement efficiency and mobility control. The model incorporates various physicochemical phenomena such as convection, dispersion, diffusion, and adsorption. Simulations of known core flooding data show that the model can simulate viscous-elastic polymer flooding mechanisms for use in feasibility evaluations, pilot plan optimization, and performance predictions for viscous-elastic polymer enhanced oil recovery.
