FIELD: gas and oil production, formation of high-intensity sound fields in stratum to increase its productivity. SUBSTANCE: gear has acoustic resonator with input part oriented towards coming flow of working agent and dissector positioned in front of resonator. Gear includes flow cavity located in flow of working agent and limiting its cross-section. Inlet part of flow cavity is manufactured in the form of one Venturi tube as minimum. Resonator and dissector are placed inside flow cavity. Bottom part of resonator has drain hole. EFFECT: enhanced efficiency of action on productive stratum thanks to increased stability of parameters of radiator both with presence of condensate in flow of working agent and with change of diameter of boreholes as well as thanks to prevention of risk of suppression of oscillations. 1 cl, 1 dwg
