摘要： A polycrystalline diamond (PCD) compact and method for making the compact are provided. The method includes bringing a first PCD wafer and a second PCD wafer together at an interface in the presence of a bonding agent to form an unbonded assembly and bonding the wafers together at the interface at a pressure and temperature at which diamond is thermodynamically stable. The first PCD wafer is more thermally stable than the second PCD wafer.

摘要： An earth-boring bit has a bit body, at least one cantilevered bearing shaft, including a base and a cylindrical journal bearing surface extending inwardly and downwardly from the bit body, and at least one cutter mounted for rotation on the cylindrical journal bearing surface of the bearing shaft. A seal assembly is disposed between the cylindrical journal bearing surface and the cutter proximally to the base of the cantilevered bearing shaft. The seal assembly includes at least one rigid seal ring having a seal face in contact with a second seal face. At least one of the seal faces is at least partially formed of a super-hard material having wear-resistance greater than, and a coefficient of sliding friction less than, that of the rigid seal ring material.

摘要： A combination metal milling and earth drilling tool, for use in performing a single trip kickoff from a casing in a well bore. The combination milling and drilling tool has a first, relatively more durable cutting structure, such as tungsten carbide, and a second, relatively harder cutting structure, such as polycrystalline diamond. The more durable first cutting structure is better suited for milling metal casing, while the harder second cutting structure is better suited for drilling through a subterranean formation, especially a rock formation. The first cutting structure is positioned outwardly relative to the second cutting structure, so that the first cutting structure will mill through the metal casing while shielding the second cutting structure from contact with the casing. The first cutting structure can wear away while milling through the casing and upon initial contact with the rock formation, thereby exposing the second cutting structure to contact with the rock formation. The second cutting structure can then be used to drill through the rock formation.
摘要翻译：一种组合的金属铣削和地面钻孔工具，用于从井筒中的套管执行单次行程启动。组合铣削和钻孔工具具有第一相对更耐用的切割结构，例如碳化钨，以及第二，相对较硬的切割结构，例如多晶金刚石。更耐用的第一切割结构更适合于铣削金属套管，而较硬的第二切割结构更适合于穿过地下地层，特别是岩层的钻孔。第一切割结构相对于第二切割结构向外定位，使得第一切割结构将铣削通过金属壳体，同时屏蔽第二切割结构而不与壳体接触。第一切割结构可以在铣削通过壳体并且与岩层初始接触时磨损，从而暴露第二切割结构以与岩层接触。然后可以使用第二切割结构钻穿岩层。
