FIELD: oil and gas industry.
SUBSTANCE: device for generating pressure waves in the injector bore is designed as the Helmholtz jet generator (HJG), containing: a cylindrical chamber of the cavity resonator with two parallel lids - front and rear; the inlet nozzle, disposed in the front lid; the ring, mounted on the radial pillars on the cylindrical chamber axis of the cavity resonator in the interval between the lids; and the outlet hole. Wherein the inlet nozzle is connected with FC and the outlet is directed downward along the borehole. Wherein the outlet is made on the side from the inlet nozzle, in the front lid or housing of the cavity resonator cylindrical chamber.
EFFECT: increasing the efficiency of low-frequency vibrations generating without increasing volume of the cavity resonator chamber or holes length.
