Key words: well drilling, drill string, rotary steerable system, screw downhole motor.
The possibility of controlling the frequency of rotation of the drill string (DS) during the operation of a motorized rotary steerable system is considered. It is shown that in order to ensure a constant rotation frequency of the bit, the rotation frequency of the DS rotation must be increased during the drilling of the entire interval.
