FIELD: oil and gas industry.
SUBSTANCE: device consists of cylindrical containers filled with reagent and equipped with end plugs connected by couplings and dosing units communicating with mixing chambers and connected hydraulically to the well. In each container there is a shaft with ends screwed into axial threaded openings of the end plugs. A dosing unit is made in the upper part of the shaft as am axial channel and radial openings communicating with it; mixing chambers are placed inside couplings. The container can be made of a fibreglass pipe or thin-wall pipe of stainless steel.
EFFECT: increase of the device capacity without increase of its mass in order to enlarge duration of the reagent supply to the well fluid.
