FIELD: oil extractive industry.
SUBSTANCE: method includes lowering tubing pipes to face. Before pumping treating compound well liquid is replaced with hydrocarbon liquid, for example, water-less oil. Treating compound is pumped and partially pushed into bed. Level of hydrocarbon liquid in well shaft is lowered down to mark at which bed pressure is in 1.5-2 times greater than face pressure. Under such conditions implosive treatment is performed. Then tubing pipes are raised to surface, ultrasound waves emitter is lowered and ultrasound treatment of face-adjacent bed area is performed range-wise in upward direction at each meter of perforated bed thickness. Method may be used in deposits with low and normal bed pressures, in wells with bad collector properties of face-adjacent bed area, and for completing wells completed by drilling and after maintenance.
EFFECT: higher productiveness.
