Abstract

СПОСОБ БУРЕНИЯ ПОРОД, включающий вращение прижатого к забою бурового инструмента, совершаемое при посто нном усилии подачи и приложении виброинерционной нагрузки, отличающий-с  тем, что, с целью повышени  скорости бурени  и износостойкости бурового ннструмента , осуществл ют периодическую остановку вращени  бурового инструмента и в момент остановки производ т закручивание бурового става в направлении вращени  бурового инструмента.A DRILLING METHOD, including rotation of a drilling tool pressed to the bottom, performed with a constant feed force and application of a vibro-inertial load, which is characterized by the fact that, the stops are made to twist the drill rod in the direction of rotation of the drilling tool.
