Oil recovery, including conventional and viscous oil, can be improved significantly by flooding with polymer solutions.
This chemical flooding method can increase oil production, and it can improve the macrodisplacement efficiency and microsweep efficiencies.
In this study, we establish physical models that include the dead-end and complex models based on the pore-network pattern etched into glass, using the snappyHexMesh solver in OpenFOAM.
These models capture the complexity and topology of porous media geometry.
We establish a mathematical model for transient flows of viscoelastic polymers using computational fluid dynamics simulations, and we study the distributions of pressure and velocity for different elasticity scenarios and different flooding process.
The results demonstrate that the pressure difference increases as the relaxation time decreases, before the flow reaches its steady state.
For a steady flow, elasticity can give rise to an additional pressure difference, which increases with increasing elasticity.
Thus, the characteristics of pressure difference vary before and after the flow becomes steady; this phenomenon is very important.
Velocity contours become more widely spaced with elasticity increase.
This suggests that elasticity of the polymer solutions contributes to the microsweep efficiency.
The results of the study provide the necessary theoretical foundation for laboratory experiments and development of methods for polymer flooding and can be helpful for the design and selection of polymers for polymer flooding.
