Impact of waves on porous media and increase in oil recovery of beds

Abstract

The results of studying wave impact on a productive bed for extraction of capillary hydrocarbons are presented. The studies were conducted on experimental equipment that which simulates filtration processes in a system of hydrodynamically related wells. Impact waves are considered that propagated from a processed well inside a bed via a system of fractures and faults with higher permeability. It is shown that impact pressure pulses intensify filtration due to the involvement of capillary hydrocarbons and to the increase in permeability of the porous medium.
