A mathematical model describing the process of displacement 
of oil by water with the use of polymer-disperse systems is proposed. 
The point of the technology consists of pumping sequentially water, 
a low-concentration polymer solution, and water with disperse particles. 
The porous medium is given in the form of two interpenetrating continua, 
one of which is associated with mobile phases and the other - 
with immobile phases. The corresponding expressions for dynamic porosity 
and the residual resistance factor have been obtained. In describing 
the mass transfer between the continua, an ideal model of a porous 
medium in the form of a bundle of capillaries of different radii and 
the pore- and particle-size distribution functions have been used.
