FIELD: oil and gas industry.
SUBSTANCE: invention can be used to optimise control over drilling process. Technical result is achieved by proposed method of optimization of drilling process, wherein control of axial load and drive shaft angular speed depending on design strategy of drilling is implemented. At that, compensation for auto-oscillations of drill string in intermediate stages of drilling strategy is carried out by dynamic increment of torque.
EFFECT: higher efficiency of control based on implementation of developed drilling strategy, increased accuracy of control, compensation of auto-oscillations of drilling column and as result is higher mechanical speed of well drilling.
