FIELD: oil industry. SUBSTANCE: invention specifically refers to underground equipment of well designed to supply reagent into product current of well. Gear for treatment of well fluid has body manufactured in the form of branch pipe housing solid reagent. Branch pipe is connected to shoe of lifting pipes and has radial conduits in its upper part. Cross- section area of these conduits is not less than cross-section area of lifting pipes. Reagent is placed into branch pipe below radial conduits and has open porosity to let upward current of well fluid pass through it and upper end of branch pipe. EFFECT: reliable metering of reagent into current of extracted fluid carried over lifting pipes. 2 dwg
