Abstract

Summary

Seismic impact on geological environments leads to acoustic currents in the pore space of reservoirs. In the present work, the structure of the flow of fluids in the pore under the conditions of superimposed oscillations was studied by numerical simulation. Pore walls were not deformed and, as a consequence, the peristaltic mechanism of flow intensification was not taken into account. The performed calculations based on the solution of the Navier-Stokes equations showed that a longitudinal elastic wave generates acoustic currents and induces a fluid flow inside the pore along the direction of wave propagation. The average velocity of such a flow is comparable with the rate of fluid filtration in productive layers. It is shown that the velocity of such a flow depends strongly on the amplitude of the oscillations of the acoustic action. The results obtained substantiate the wave methods of impact on the formation to improve the efficiency of oil production.
