FIELD: mining.
SUBSTANCE: device comprises a container with a breathing hole in which a deformable shell filled with a liquid reagent is placed and a metering peristaltic pump with an elastic tube cooperating with the rotor by means of pressure rollers. The drive of the peristaltic pump is a hydro turbine, the shaft of which is connected through a reducer to the rotor of the peristaltic pump. The hydraulic turbine is covered from below by a sealing element abutting against the wall of the borehole and is brought into rotation by the formation fluid.
EFFECT: reliability of the dispensed feed of the reagent is increased by providing it with an autonomous energy source.
