    摘要： An improved cutter for fixed cutter drill bits includes a base portion with a longitudinal axis that extends through a center of the base portion and a cutting face which is generally centered with the base portion. The cutting face has a periphery edge geometry comprising a first arcuate segment and a second arcuate segment spaced apart and arranged opposite each other with linear edge segments disposed there between forming sides of the cutting face. The cutting face spans a maximum edge-to-edge dimension L in a first direction that corresponds to a major axis of the cutting face. The cutting face spans a maximum edge-to-edge dimension W in a second direction, which is perpendicular to the first direction, and W is less than L.

    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 composites comprise a polycrystalline diamond body having a plurality of ultra-hard discrete regions dispersed within a polycrystalline diamond second region. The plurality of discrete regions has an density different from of the polycrystalline diamond second region. A metallic substrate can be joined to the body. The discrete regions can be relatively more thermal stable than, have a higher diamond density than, and/or may comprise a binder material that is different from the polycrystalline diamond second region. Polycrystalline diamond composites can be formed by combining already sintered granules with diamond grains to form a mixture, and subjecting the mixture to high pressure/high temperature conditions, wherein the granules form the plurality of discrete regions, or can be made by forming a plurality of unsintered granules, combining them with diamond grains to form a mixture, and then subjecting the mixture to first and second high pressure/high temperature conditions.

    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.
