Abstract
1. Буровое долото с поликристаллическими алмазными элементами, включающее цилиндрический корпус с резьбой для присоединения к колонне бурильных труб и с боковыми армирующими элементами PDC по его диаметру, простирающиеся вниз лопасти с резцами PDC для разрушения породы, внутренние полости и каналы для подачи промывочной жидкости к забою, твердосплавные насадки, установленные на выходе из этих каналов, отличающееся тем, что наружная поверхность боковых поликристаллических алмазных элементов наклонена к армируемой поверхности под острым углом в пределах от 2 до 6° в сторону вращения долота, а самые высокие их части расположены на максимальном диаметре долота заподлицо с поверхностью корпуса. ! 2. Буровое долото по п.1, отличающееся тем, что боковые армирующие элементы с плоской торцовой поверхностью, перпендикулярной их оси, устанавливаются в отверстия, оси которых наклонены к армируемой поверхности под острым углом от 2 до 6° в сторону вращения долота. ! 3. Буровое долото по п.1, отличающееся тем, что сами боковые армирующие элементы, выполненные с наклоном торцовых наружных поверхностей под острым углом от 2 до 6° к своей оси, установлены в отверстия, оси которых выполнены по радиусам корпуса, с постоянной ориентацией указанного наклона в сторону вращения долота.1. A drill bit with polycrystalline diamond elements, including a cylindrical body with a thread for connecting to the drill pipe string and with PDC lateral reinforcing elements along its diameter, blades extending downward with PDC cutters for rock destruction, internal cavities and channels for supplying flushing fluid to the bottom , carbide nozzles installed at the outlet of these channels, characterized in that the outer surface of the side polycrystalline diamond elements is inclined to the reinforced surface under a sharp glom in the range from 2 to 6 ° in the direction of rotation of the bit, and their highest parts are located on the maximum diameter of the bit flush with the surface of the body. ! 2. The drill bit according to claim 1, characterized in that the lateral reinforcing elements with a flat end surface perpendicular to their axis are installed in holes whose axes are inclined to the reinforced surface at an acute angle from 2 to 6 ° in the direction of rotation of the bit. ! 3. The drill bit according to claim 1, characterized in that the lateral reinforcing elements themselves, made with a slope of the end outer surfaces at an acute angle from 2 to 6 ° to their axis, are installed in holes whose axes are made along the radii of the body, with a constant orientation the indicated inclination in the direction of rotation of the bit.
