FIELD: oil and gas industry.
SUBSTANCE: device for making perforation tunnels in a well which is installed at the casing string includes a body, a wedge with groove, a hydraulic cylinder and at least one operating device with jet tunnel placed at the support groove and the wedge with potential radial reciprocative movement. The wedge is installed above a piston of the hydraulic cylinder where the support of the operating device is fixed and the cavity below the piston is communicated by means of tubes with jet tunnel of the operating device and the cavity over the cavity of the operating fluid delivery.
EFFECT: manufacturing of small-size device that provides increase in reliability and efficiency of the productive formation processing with reduction of material costs.
