    摘要： A bottom hole assembly containing a drill bit. The drill bit additionally has a plurality of primary cutter elements mounted thereto. The plurality of cutter elements comprise one or more first cutter elements and one or more second cutter elements. The second cutter element differs from the first cutter element in at least one cutter element property. The first cutter element has a diamond body containing a first region comprising an infiltrant material disposed within the interstitial regions. The first region is located remote from the working surface of the diamond body. The first cutter element also contains a second region comprising interstitial regions that are substantially free of the infiltrant material. The second region is located along at least the working surface of the diamond body. Also included are a cutter element, method of designing a bottom hole assembly as well as method of designing a drill bit.

    摘要： Polycrystalline diamond constructions comprises a diamond body attached to a metallic substrate, and having an engineered metal content. The body comprises bonded together diamond crystals with a metal material disposed interstitially between the crystals. A body working surface has metal content of 2 to 8 percent that increases moving away therefrom. A transition region between the body and substrate includes metal rich and metal depleted regions having controlled metal content that provides improved thermal expansion matching/reduced residual stress. A point in the body adjacent the metal rich zone has a metal content that is at least about 3 percent by weight greater than that at a body/substrate interface. The metal depleted zone metal content increases gradually moving from the body, and has a thickness greater than 1.25 mm. Metal depleted zone metal content changes less about 4 percent per millimeter moving along the substrate.

    摘要： A cutter for a fixed cutter drill bit including a substrate and an ultrahard material layer disposed on an end surface of the substrate, the ultra hard material layer having an upper surface opposite the substrate end surface and a peripheral surface such that the upper surface intersects the peripheral surface along a peripheral edge. The peripheral edge continuously increases and decreases in height as measured from a plane perpendicular to a longitudinal axis of the cutter.
