FIELD: oil production industry. SUBSTANCE: according to method, injected into each interlayer simultaneously and separately are solutions of polymers. Injected into high-permeable interlayers are polymers of high molecular mass, and injected into low-permeable interlayers are polymers of low molecular mass. Polymer is selected basing on condition that average size of macromolecules is less than average diameter of porous passages. EFFECT: high efficiency.
