摘要： A cutter for a drill bit used for drilling wells in a geological formation includes an ultra hard working surface and a chamfer along an edge of the working surface, wherein the chamfer has a varied geometry along the edge. The average geometry of the chamfer varies with cutting depth. A depression in the shaped working surface is oriented with the varied chamfer and facilitates forming the varied chamfer. A non-planar interface has depressions oriented with depressions in the shaped working surface to provide support to loads on the working surface of the cutter when used.

摘要： Diamond bonded constructions comprise a diamond body attached to a substrate, wherein the body includes a first diamond bonded volume, and a second diamond bonded volume attached thereto. The second volume may be provided in the form of a powder or a presintered mass prior to attachment, and the first volume may be provided in the form of presintered pieces when combined with the second volume. The first volume diamond volume content is greater than about 94 percent, and is the same or greater than that of the second volume. The first volume is sintered during a first HPHT process, and the second volume is sintered and/or attached to the first volume during a second HPHT process. The first HPHT pressure is greater than the second HPHT pressure. The substrate is not an infiltration substrate used to form the first diamond volume. The diamond body may be thermally stable.

摘要： Diamond bonded construction comprise a diamond body attached to a support. In one embodiment, an initial substrate used to sinter the body is interposed between the body and support, and is thinned to less than 5 times the body thickness, or to less than the body thickness, prior to attachment to the support to relieve stress in the body. In another embodiment, the substrate is removed after sintering, and the body is attached to the support. The support has a material construction different from that of the initial substrate, wherein the initial substrate is selected for infiltration and the support for end use properties. The substrate and support include a hard material with a volume content that may be the same or different. Interfaces between the body, substrate, and/or support may be nonplanar. The body may be thermally stable, and may include a replacement material disposed therein.
