FIELD: oil and gas industry.
SUBSTANCE: operation optimisation of drill bit hydraulically driven by rotor and stator, during drilling of the wellbore in soil. The drilling optimisation provides for measurement of the first set of operation parameters of the rotor and stator, including rotation speed of the rotor and rotor torque for the first time period, generation of the first set of ratios from the first set of the operation parameters for this to ensure forecast of the rotor speed and rotor torque in the range of operation parameters, determination based on the ratios of the first more optimal operation mode, and change of at least one operation parameter to move the rotor and stator work towards the more optimal operation mode.
EFFECT: drilling optimisation.
