摘要： A method of forming polycrystalline diamond includes providing an alloy over at least portions of a plurality of diamond particles, and subjecting the plurality of diamond particles to a high-temperature, high-pressure process to form a polycrystalline diamond material having inter-granular bonds between adjacent diamond particles. The alloy includes iridium and nickel, and a volume of the diamond particles is at least about 92% of a total volume of the alloy and the diamond particles. The polycrystalline diamond material includes at least about 92% diamond by volume. A polycrystalline diamond compact includes grains of diamond bonded to one another by inter-granular bonds and an alloy disposed within interstitial spaces between the grains of diamond. The grains of diamond occupy at least 94% by volume of the polycrystalline diamond compact. An earth-boring tool may include a bit body and such a polycrystalline diamond compact.

摘要： The present invention provides a drill bit (1 ), and a method for its manufacture, that is suitable for use within a casing drilling process. The drill bit (1 ) comprises a monolithic body (5, 6, 8) made from bronze, e.g. aluminium bronze or nickel aluminium bronze, and a relatively hard material mounted thereon. The hard material may comprise polycrystalline diamond (PDC), tungsten carbide or cubic boron nitride. In one embodiment the monolithic body comprises a crown (6) and a plurality of cutting members (5). The hard material may be mounted directly on the crown or, alternatively, on the cutting members (5). The described drill bit (1 ) facilitates the drilling of hard rock formations while still being capable of being drilled through by a standard oilfield drill bit.

摘要： Изобретение относится к пород оразрушающему инструменту, применяемому для бурения нефтяных и газовых скважин, особенно для бурения наклонно направленных и горизонтальных скважин и пород, представленных чередованием пропластков различной твердости. Технический результат - улучшение управляемости с одновременным повышением виброустойчивости долота PDC за счет применения специального композиционного покрытия и регулировки выступания резца над этим покрытием. Буровое лопастное долото включает корпус с присоединительной резьбой, центральным каналом и выходными отверстиями для промывочной жидкости, и лопастями, оснащенными поликристаллическими алмазными резцами PDC. Поверхность лопастей снабжена композиционным покрытием, имеющим различную износостойкость по толщине, при этом стойкость композиционного покрытия к абразивному износу увеличивается в направлении от наружной поверхности к нижележащим слоям, а величина выступа резцов вблизи центра долота над поверхностью композиционного покрытия заведомо меньше необходимого для бурения самых твердых пород в данном геологическом разрезе.
