FIELD: oil and gas production.
SUBSTANCE: procedure consists in pumping gas-liquid mixture into borehole of well, also, mixture is prepared with usage of process water, water-soluble surface active substance and nitrogen, and in pressurising gas-liquid mixture from well borehole completely into bottomhole zone of reservoir with fluid compensating reservoir pressure. Degree of dispersion of gas-liquid mixture and time for conditioning in the bottomhole zone of the reservoir are determined from the condition of formation of structured viscous-elastic spacer zone impermeable for oil and gas between reservoir fluid and the borehole of the well.
EFFECT: raised efficiency and processability of the well killing procedure due to replacement of gas and oil front into depth of bottomhole zone of reservoir and due to gradual self-adaptation and conversion of well to operation mode after repair.
