FIELD: drilling equipment; applicable in drilling of controlled directional and horizontal wells with the help of screw downhole motor. SUBSTANCE: essence of invention consists in that motor with angle of curving transmitter of angle of curving mechanism rotates nut of screw pair whose screw turns ball unit under effect of inclined surface of bushing hole to install ball unit to position at which angle of curving equals zero which is measured by angle of curving transmitter. Then motor with position pickup of mechanism for changing the angle of deflector turns through reducing gear the cylinder bushing to preset position (by azimuth) and motor of angle of curving mechanism is engaged to move cylindrical bushing to attain the preset angle of curving by signals from inclinometer system. EFFECT: higher productivity of work due to remote control of angle of curving of screw downhole motor and bottom-hole assembly of drill string in preset plane. 1 dwg
