The article discusses the differential equation of the stationary two-phase filtration, the obtained as a spe-cial case of nonlinear non-stationary equations. It is established that for the formulation of solutions it is necessary to use the dependence of water-saturation and oil-saturation factors on the pressure of water pumped into the reservoir. With the advance bringing into the development of the injection well, it has been established, that the water and oil flow rates and the water-cut coefficient depend on the selected coefficients of the relative permeability and the outer boundary of the drainage area. The merits and demerits of the stationary filtration model are estimated.
