FIELD: oil and gas industry.
SUBSTANCE: method includes power measurement of engine being the rotor drive, measurement of speed of rotation of drive shaft. At that to the channel of measurement of torque surge the inverting operation is included, and power of rotor drive engine is regulated according to harmonic law with frequency equal to frequency of change of torque surge, and that control harmonic oscillations are shifted by phase relatively to the harmonic oscillations of torque surge by 180°.
EFFECT: simplified structure of control system, increased control accuracy, optimization of measurement systems, reduced vibrations of drilling string, and hence increased speed of well drilling.
