The article discusses issues related to the vibrations of drillstring (DS). The relevance of the fight against torsional fluctuations DS and the reasons for their occurrence are analyzed. The hydromechanical method of control of torsional oscillations DS and device for its implementation is proposed. This method is characterized by its versatility and practically does not depend on the conditions of well drilling. Characteristics of the developed control method are determined by means of the hydraulic model of drilling mud behavior. The model illustrates the operability of the method and can assist in the selection of parameters for regulator design.
