成果简介	NOVELTY - The drill bit has a bit portion that is connected to a bottom hole assembly by a thread. The blades are equipped with fixed equipment in the form of polycrystalline diamond cutters (PDC). The rotating roller elements are located in the mounting surface of the blade, and into the portion of spherical hard-alloy tungsten carbide inserts are inserted, fixed with screws in the area of contact between the calibrating unit of the blade and the borehole walls. The cutting cutters are located on the calibrating unit of the blade. The inserts are made of synthetic diamond or in the form of a hard alloy surfacing. The blades are arranged parallel to the longitudinal axis of the bit or at an angle to the axis. The roller elements are located either parallel to the vertical axis of the bit or with a slight deviation at a certain angle from the vertical axis. USE - Vibration-resistant hybrid drill bit.
