FIELD: oil and gas industry.
SUBSTANCE: method involves injection of polymer compound based on resin to treated well interval. For geological technical characteristics of a certain well optimum percentage of components of each portion of water-soluble polymer compound containing epoxy-phenylene resin, hardener, water is determined. The first portion of water-soluble polymer compound with viscosity 29.575-512.881 MPa/s and the second portion of water-soluble polymer compound with viscosity 512.881-878.37 MPa/s are prepared, the first portion of water-soluble polymer compound is added to treated well interval, then the second portion is added, portions of water-soluble polymer compound are forced-through by process liquid, then composition polymerisation and well washing are performed. As per the other version, the isolation method of water influxes to well includes injection of polymer compound based on resin containing epoxy-phenylene resin, hardener, water. At first water-soluble polymer compound is prepared, the composition is added to treated well interval and forced-through by process liquid, then composition polymerisation is performed.
EFFECT: increasing efficiency of the isolation method.
