Updating of the hardware system of mode regulation of a drill string operation based on the measurement of torque dynamic parameters
The article analyzes the systems of mode regulation of a drill string operation. The reasons for the occurrence of self-oscillations and a drill string wobbling against a well’s walls, confirmed by the results of the experiment are discussed. The borders an area of a drill string’s vibration-free operation are defined and control parameters that ensure mode regulation of a drill string operation are justified. The ways of modernization of the hardware system of regulation of a drill string operation mode based on the measurement of torque dynamic parameters are outlined.
