摘要： An abrasive-impregnated cutting structure for use in drilling a subterranean formation is disclosed. The abrasive-impregnated cutting structure may comprise a plurality of abrasive particles dispersed within a substantially continuous matrix, wherein the abrasive-impregnated cutting structure exhibits an anisotropic wear resistance. One or more of the amount, average size, composition, properties, shape, quality, strength, and concentration of the abrasive particles may vary within the abrasive-impregnated cutting structure. Anisotropic wear resistance may relate to a selected direction, such as, for example, one or more of an expected direction of engagement of the abrasive-impregnated cutting structure with the subterranean formation and an anticipated wear direction. Anisotropic wear resistance of an abrasive-impregnated cutting structure may be configured for forming or retaining a formation-engaging leading edge thereof. A rotary drag bit including at least one abrasive-impregnated cutting structure is disclosed.

摘要： The residual stresses that are experienced in polycrystalline diamond cutters, which lead to cutter failure, can be effectively modified by selectively thinning the carbide substrate subsequent to high temperature, high pressure (sinter) processing, by selectively varying the material constituents of the cutter substrate, by subjecting the PDC cutter to an annealing process during sintering, by subjecting the formed PDC cutter to a post-process stress relief anneal, or a combination of those means.

摘要： Cutting elements providing a relatively constant superabrasive area in contact with the formation responsive to weight on bit during a substantial portion of the useful life of a circular cutting face cutting element or other cutting element exhibiting a non-linear cutting edge, for example, from about 5% diametrical wear to in excess of about 30% diametrical wear in the case of a circular cutting element, measured across the cutting face. The superabrasive table of the cutting element is configured, internally, externally, or both, to vary in depth radially and laterally, as required, so that an increase in width of the contact or wear flat area with the formation and the variation in table depth as the cutting element wears, are substantially offsetting. The rate of penetration of a drill bit so equipped may thus be maintained at a desirable magnitude without a substantial increase in weight on bit as the cutting element wears, since the superabrasive contact area is maintained relatively constant.
摘要翻译：在圆形切割面切割元件或其他显示非线性切割边缘的切割元件的大部分使用寿命期间，响应于钻头上的重量，提供与地层接触的相对恒定的超研磨区域的切割元件，例如从约在切割面上测量的圆形切割元件的情况下，5％的直径磨损超过约30％的直径磨损。切割元件的超级磨床在内部，外部或两者上配置，以根据需要在径向和横向上进行深度变化，使得接触的宽度增加或者与地层的平坦区域的磨损以及台面深度的变化当切割元件磨损时，基本上是偏移的。因此，由于超级磨料接触面积保持相对恒定，所以如此装备的钻头的穿透速度可以保持在期望的幅度，而不会随着切削元件磨损而在钻头上的重量显着增加。
