The Law Of The Unsteady Flow Of The Polymer Aqueous Solution-Base Foam Through Porous Media

The polymer aqueous solution-base foam is a chemical flooding enhanced oil recovery technology of the polymer-surfactant solution as the liquid of foam as a displacement agent flooding ,it can provide a theoretical guidance for this chemical flooding technique to study of the law of flow of the polymer aqueous solution-base foam through porous media.Based on the rheological behavior of the liquid phase of the polymer aqueous solution-base foam which was described by the power-law model, the model of one-dimensional unsteady flow of the polymer aqueous solution-base foam through porous media was established; the method of the numerical calculated of one-dimensional unsteady flow of the polymer aqueous solution-base foam through porous media was given;The program"The Numerical Calculationof the Unsteady Flow of the Polymer Aqueous Solution-Base Foam through Porous Media"was programmed using VB6.0.Taking 0.001wt% polyacrylamide (HPAM) and 0.830wt%α-Olefin Sulfonate (AOS 1416) aqueous solution-base foam as anexample, the program was applied to calculate and analyze one-dimensional unsteady folw of it in Boise core.
