Abstract: A laboratory study including physical modeling of filtration processes in porous beds with similarity criteria satisfied is performed. It is demonstrated that weak dynamic actions on stressed host rock blocks can initiate repacking of the system of blocks, leading to an increase in pressure in the productive bed and in oil recovery.

Keywords: increase in oil recovery, filtration, unsteady action, laboratory experiment, similarity criteria.
