The invention relates to gas and oil producing industry, in particular to devices used for secondary production reservoir exposing with mechanical treatment thereof. A device for secondary production reservoir exposing with mechanical treatment thereof comprises a body with a drive arranged therein for rotating and feeding a drilling means embodied as a frame with a flexible working member, a longitudinal guiding groove is made in the frame, the frame has a drive sprocket, the drilling means is kinematically connected to the drive, the body is provided with a mechanism for fixing to the borehole wall, wherein the drilling means is hinge fixed on the body, with a hydrosystem additionally arranged therein comprising a pump, a hydraulic cylinder with a spring-loaded rod, an overpressure valve and a capacity for oil, the pump is kinematically coupled with the drive and connected to the a hydraulic cylinder with a spring-loaded rod, which, via the overpressure valve is connected to the oil capacity, and the hydraulic cylinder rod is adapted to move in the frame groove. Rotation of the driving sprocket for moving the flexible working member and turn of the drilling means are carried out through a hydraulic drive or an electric drive, while a mechanism for fixing to the borehole wall is embodied as a hydraulic cylinder with a rod and a return spring. The inventive result is aimed at enhancing reliability due to the use of hydraulically controllable feed to a frame turn, providing safe removal of the drilling means from a borehole. |
