FIELD: oil-and-gas production.
SUBSTANCE: method includes alignment of filtration and strength characteristics of bore by water jets and pumping of plugging and/or gel-forming mixture with ability of following control of airtightness of bore with hydraulic test of stratum after each stage of insulation.
EFFECT: increasing of airtightness and strength of bore in joint ranges with incompatible geological-and-physical conditions of drilling, enhancement of structures of depth wells.
