FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to oil industry, particularly, to drilling wells, and may be used to control turbodrill rpm and drilling process. Proposed method comprises the following jobs: ground resonator is additionally arranged in pressure line and revolving downhole resonator is installed above turbodrill. Note here that the following steps are executed: generation of wide-band spectrum of sound frequencies by drill pump into pressure line, redistribution of frequencies power in spectrum generated by said drill pump in the low-frequency range generated by ground resonator, generation of wide-band spectrum of sound frequencies by revolving downhole resonator rigidly coupled with turbodrill shaft into drilling string inner space, periodic redistribution of frequencies power in spectrum generated by turbodrill in the low-frequency range generated by revolving downhole resonator in proportion to turbodrill shaft rpm.
EFFECT: higher reliability of control over turbodrill shaft rpm and drilling process.
