Description

при использовании изобретени  в процессе бурени  скважин дополнительное высокочастотное ударное воздействие долота па забой (в период его контакта с забоем) происходит посто нно, что обеспечивает иптснспвиое разрушение породы. Причем дополнительное разнонаправленное ударное воздействие, передаваемое цилиндрическим грузом 7 снар ду, снижает веро тность его прихвата на забое скважпны.When using the invention in the process of drilling wells, an additional high-frequency percussive impact of the bit on the bottomhole (during its contact with the bottomhole) occurs continuously, which provides for the destruction of the rock. Moreover, the additional multidirectional shock effect transmitted by the cylindrical load 7 to the tool reduces the likelihood of its sticking to the bottom of the borehole.
