In surfactant-polymer binary flooding, to study the effects of polymer in emulsion seepage flow rules in porous medium, artificial sandstone cores were established to carry out the experimental analysis. Biology microscope and sample analytic control methods were employed for all samples. Results displayed that polymer can increase the strength of the interfacial film, and water phase viscosity would increase with the existence of the addition polymer, which reduces the floating speed of emulsified droplets and boosts the emulsion stability. The bigger polymer relative molecular weight is, the easier molecular chain intertwines. With the shear force in porous media, polymer has been cut into small molecular chain segments and the diffusivity of emulsion droplets increases. The multilayer three-dimensional network structure in the polymer solution contributes to form O/W emulsion. Under the interfacial tension of 10-3 grade, porous media has a strong shearing effect on fluid. As the velocity gets larger, the initially status dominated by two phases fluid flow is transformed into emulsion flow mode gradually.
