It is determined that main reasons of permeability reservoirs decrease in Nizhnechutinskoe oil field are capillary pressures and elastic stresses, appearing at depression making. It is displayed that to reduce tangential stresses in oil bearing reservoirs it is expedient to make vertical slits in oilwells’ open holes.
