The paper studies the influence of superimposed oscillations on the flow of a liquid in a porous medium. The object of the study is a three-dimensional pore space, obtained by the results of Х-ray microtomography of a synthetic porous medium. Physically, models of porous samples are created from microscopic glass beads by sintering in a muffle furnace. The flow of fluid in the pore space is described by the continuity and Navier-Stokes equations. Computer modeling was carried out for both stationary flow and flow with superimposed oscillations. The regularities of the flow and the influence of superimposed vibrations on them are determined. The obtained data can be used to improve the methods of wave action on productive formations for oil production.
