Authors: G.M. Panakhov, N.N. Abbasova (Institute of Mathematics and Mechanics of Azerbaijan National Academy of Sciences, Azerbaijan Republic, Baku)

Key words: porous medium, capillary pressure, hydrodynamic pressure, inhomogenity, oil saturated collector

The paper presents results of research on the optimization of water flooding method by successive periodic increase in hydrodynamic pressure to extract capillary clamped oil. Method provides a consistent accounting, as the displacement conditions and filtration characteristics of fluid-saturated reservoirs. Estimating calculations allow to determine the duration and phasing control of injection pressure as the conditions for achieving the expected in oil recovery increasing.
