FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to the oil-and-gas industry and can find application in the elimination of well water production or behind-the-casing flow. The proposed method comprises cutting the production string interval, making a cavity and filling the latter. For this, the system of water-swelling packers is used consisting of at least 4 water-swelling elements, at least 2 of which are located opposite the cut interval to fill the cavity at swelling. Holding is executed for the swelling of the packers.
EFFECT: perfected method.
