The generalized law of multiphase filtration, which explicitly takes into account the viscous interaction between fluids, capillary and gravitational effects, is analyzed. A special case is considered – a two-phase filtration flow as the basis of the technology of oil reservoirs flooding. A method for determining new material functions – «coupling» phase permeabilities, and their quantitative contribution to the field development indicators is given. A new effect of the dependence of capillary forces on the direction of flow in anisotropic media has been revealed.
