FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil industry, in particular, to installation for water insulation works in well. Installation comprises a reservoir for storage and preparation process solutions and liquids and components thereof, mixing unit for preparation of insulating compound in a volume exceeding internal volume of well from bottomhole to upper boundary of perforation interval, pump unit for filling insulating compound through filling pipe string in well to upper boundary of perforation interval with flushing into formation using process liquid, control unit for control of preparation of solutions and liquids and their injection into well, input unit for inputting into control unit configuration of formed insulating bridge, including current position of perforation interval, wherein control unit controls parameters of insulating compound and controls injection of insulating compound into well on basis of preset configuration of created insulating bridge.
EFFECT: technical result is high efficiency and reliability of water shutoff in well.
