Fluid-Solid Coupling Seepage-Based Numerical Simulation of Mechanical Oil Expression from Peanut

Abstract

In view of effect offluid-solid coupling on flow of oil fluids through media and effect of rheology on fluid' solid coupling, the numerical simulation models of mechanical oil expression from vegetable oil were developed. The models were solved by using of combining finite difference with finite element. The displacement experiments for extracted peanut were used to validate the models. The predicted values are in good agreement with the measured ones.

Class II Reservoir Polymer Injection Parameters Impact on the Oil Displacement Efficiency

“…This is because higher relative molecular mass may increase the tackifier effect of the solution and the amount of the polymer retention, which results in higher residual resistance factor and expands the swept volume. However, when relative molecular mass of the polymer exceeds the certain limit, the radius of molecular is larger than the pore radius [11,12]. Big polymer molecular may block the formation and the injected pressure may be increased, which will decrease the swept volume of the polymer flooding.…”
