REGULATION OF THE ROTATION FREQUENCY OF THE ELECTRIC DRIVE OF THE BIT IN ROTARY DRILLING OF WELLS FOR OIL AND GAS PRODUCTIONS

The operation of drilling equipment is examined, and based on an analysis of the information obtained, the rotary nature of the drilling process is determined as the primary one used in the oil and gas industry. Relationships between the rotational speed of the rotor table and the well depth, the type of bit, and the characteristics of the rock at the bottomhole are obtained; an en-gineering method for calculating the rotational speed, power, and maximum torque required for rotation of the drill string during the operation of the bit at the bottomhole is proposed
