FIELD: oil and gas industry.
SUBSTANCE: sealant for well isolation work consists of a synthetic resin and a hardener. The sealant additionally contains the corrosion inhibitor INCORGAZ-21T; the synthetic resin is an epoxy composition XT-116 component A, and the hardener is a cold-setting hardener XT-116 component B in the following proportions, vl %: The epoxy composition XT-116 component A - 70-74; the cold-setting hardener XT-116 component B - 10-14; the corrosion inhibitor INCORGAZ-21T - the rest with the proportions (weight parts) of the cold-setting hardener XT-116 component B and the epoxy composition XT-116 component A making 1:6.5-8.6 respectively.
EFFECT: invention enables higher effectiveness of the isolation work.
