DOWNHOLE TOOL

FIELD: petroleum industry. ^ SUBSTANCE: invention is referred to downhole tools, i.e. tools used in wells. The tool includes axle drive provided with connection of electric power cable installed upwards the wellbore and fastening mechanism engaged downhole between the first configuration to prevent rotational and axial movement of the unit and the second configuration to move the fastening mechanism in axial direction, axle drive which moves the fastening mechanism in axial direction downwards the wellbore, when in the second configuration, motor installed in well end of the drive, hydraulic pump connected to the motor and provided with hydraulic power source and functional part connected below the hydraulic pump and powered by such pump, operation of axle drive ensuring axial movement of the functional part downwards the wellbore. Invention ensures run RIH with slickline and is capable of ensuring sufficient weight on bit and torque required to achieve efficient drilling. ^ EFFECT: capability to ensure sufficient weight on bit and torque required to achieve efficient drilling. ^ 22 cl, 10 dwg
