The geomechanical model has been developed, that describes variation of filtration regime in a productive stratum under influence of induced stress redistribution in the surrounding block-structured rock mass. The article shows that the surrounding rock mass may be in metastable states that can be disturbed by weak external effects, which results in the change in the stratum pressure, and the well production grows. The laboratory installation for physical simulation of such processes has been developed and manufactured based upon similarity criteria. It is theoretically substantiated and experimentally proved that it is possible to enhance oil recovery by 5-7% at late stage of reservoir development.
