FIELD: mining.
SUBSTANCE: completion assembly includes casing pipe adapted for being installed into the well shaft in underground formation and containing at least one permeable shank, one or several jet nozzles creating the fluid medium jet and located about the casing pipe, fluid medium supply tool located in the casing pipe and capable of being moved along the casing pipe, layout of the doubled packer, which can insulate the fluid medium supply tool from the annular space formed between the fluid medium supply tool and casing pipe. Well completion method involves the following stages: equipage of casing pipe; equipage of one or several jet nozzles; equipage of fluid medium supply tool; equipage of doubled packer layout; performance of well completion operation.
EFFECT: providing the possibility of translational movement along the casing string and supply of reagent in the strongly defined place owing to localisation of the space.
