FIELD: oil and gas industry.
SUBSTANCE: group relates to the method of sealing of casing pipe section in the well, wherein the section contains several leak points, perforation holes and/or places of casing pipe loosening, or other defects. The method includes measurement of the casing pipe characteristics, determination of the section location, determination of the section length along the casing pipe longitudinal direction, determination of section part and this part length where the casing pipe characteristics are within the required range of values, wherein said part passes in the longitudinal direction of the casing pipe, location of the first shutter with bridging of the first area of the casing pipe part, location of the second shutter with bridging of the second area of the casing pipe part, expansion of the first shutter and expansion of the second shutter.
EFFECT: increased sealing quality.
