FIELD: mining.
SUBSTANCE: system consists of motor unit, containing motor for creating torque and axial propeller for creating axial force, and blocking system for securing motor and axial propeller in well. The motor unit additionally has a driving shaft for transmission of torque. The system additionally includes the first and the second connector to transmit torque and axial force from the motor unit to the unit of a drill string. The first connector is designed to be connected with the unit of the drill string to transmit only axial force to a drilling tube and for transmitting torque to the additional driving shaft, installed in the drilling tube. The second connector is intended to be connected with the unit of the drill string to transmit both axial forth and torque to the drilling tube.
EFFECT: possibility to change direction of drilling curvilinear borehole without removing drilling assembly from well.
