    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: 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.
