FIELD: oil extraction industry. SUBSTANCE: layer portion being isolated is attacked with vibrowaves, and attack is maintained both before and during pumping of isolating compound. Vibrowave attack before pumping of isolating compound into the layer is performed together with hydraulic swabbing and repressions and/or depressions. Isolating compound or at least one of its components is previously treated by resilient vibrations. EFFECT: increase of layer coverage by isolating substances combined with decrease of force pumping pressure, increased selectiveness of compound intrusion, increase of holding ability of isolating screen and possible savings of isolating substances components. 23 cl, 3 tbl, 5 ex
