1. Способ регулирования процесса бурения путем измерения упругих колебаний, возникающих при взаимодействии породоразрушающего инструмента с забоем скважины, и поддержания рабочей частоты n вращения породоразрушающего инструмента на частоте, при которой при заданном значении осевой нагрузки вибрации отсутствуют, отличающийся тем, что периодически контролируют максимальную и минимальную частоту nmax, nmin вращения породоразрушающего инструмента, при которой возникают вибрации, и при их изменении дополнительно регулируют рабочую частоту n вращения породоразрущающего инструмента.1. The method of regulating the drilling process by measuring the elastic vibrations arising from the interaction of the rock cutting tool with the bottom of the well and maintaining the working frequency n of the rotation of the rock cutting tool at a frequency at which there are no vibrations at a given value of the axial load, characterized in that the maximum and minimum are periodically monitored frequency n m a x, n m i n of rotation of cutter tool in which vibration occurs and when changing the working portions adjusted further n porodorazruschayuschego the rotating tool. 2. Способ по п. 1, отличающийся тем, что определяют интервал частот N между максимальной и минимальной частотами nmax и nmin вращения, при которых возникают вибрации, а рабочую частоту n выбирают в интервале N*, расположенном внутри интервала N и границы которого на 1/3 удалены от границ интервала N.2. The method according to p. 1, characterized in that they determine the frequency interval N between the maximum and minimum rotation frequencies n m a x and n m i n at which vibrations occur, and the operating frequency n is selected in the interval N * located inside the interval N and whose boundaries are 1/3 removed from the boundaries of the interval N. 3. Способ по п. 2, отличающийся тем, что периодически изменяют рабочую частоту n вращения породоразрушающего инструмента и по мере изменения границ интервала N выбирают соответствующими ему границы интервала N*.3. The method according to p. 2, characterized in that periodically change the operating frequency n of the rotation of the rock cutting tool and as the boundaries of the interval N are changed, the boundaries of the interval N * are selected corresponding to it. 4. Способ по п. 1, отличающийся тем, что изменяют осевую нагрузку на породоразрушающий инструмент. 4. The method according to p. 1, characterized in that the axial load on the rock cutting tool is changed.
