FIELD: mining.
SUBSTANCE: invention can be applied in oil yield increase and well product watering reduction at the wells in a formation with variable permeability. The process of heterogenic oil-bearing formation development involves injection of dispersion of chemically obtained gel particles in water polymeric solution into the formation. A linear polymer is applied with the following component ratio, mass %: gel particles 0.17-1.0, linear polymer 0.25-1.8, water - the rest.
EFFECT: improved development efficiency due to higher dispersion permeability in the formation.
