FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil and gas industry and is meant for performing waterproof work in the well. Method involves subsequent pumping to the well of the composition for plugging the bed being isolated and the composition for increasing bottom-hole zone permeability. Sodium water glass with silica module 2.3-5.5 is used as the composition for plugging the bed being isolated, and isopropyl alcohol which at the same time is the additional hardener of the composition for plugging the bed being isolated is used as the composition for increasing bottom-hole zone permeability.
EFFECT: increasing efficiency of waterproof work performed in the well with heterogeneous beds as to permeability.
