摘要： A rotary drill bit for drilling a subterranean formation may comprise a bit body, a cutting element coupled to the bit body, and a torque-generating assembly configured to apply torque, either continuously or periodically, to the cutting element. The torque-generating assembly may be powered by the rotary motion of the rotary drill bit or may be hydraulically or electrically powered. The cutting element may comprise a substrate, a table of superabrasive material disposed on an end of the substrate, and at least one impelling feature formed along the exterior surface of the substrate. In addition, a method of rotating a cutting element coupled to a drill bit for drilling a subterranean formation may comprise providing a cutting element comprising a table bonded to a substrate, coupling the substrate of the cutting element to a drill bit body, and applying torque to the substrate of the cutting element.

摘要： A cutter for a drill bit has a superabrasive member joined to a substrate at a three-dimensional interface. The three-dimensional interface comprises a protrusive pattern of interconnected elements comprising projections of the superabrasive member into the substrate and vice versa. The protrusive pattern comprises at least one generally annular member intersected by a series of generally radially extending members for distributing stresses along the interface, enhancing compressive strength, and enabling optimization of the magnitudes and locations of beneficial residual stresses in the superabrasive member and in the vicinity of the substrate.

摘要： This invention discloses a drilling structure having body a defining at least one primary channel and at least one secondary channel therein to initiate and maintain recirculation of an amount of drilling fluid back through the secondary channel to maintain positive, independent flow of drilling fluid through each primary channel of the drilling structure. The recirculation of drilling fluid is encouraged by providing a recirculation passageway in fluid communication with the primary channel defined by a portion of the body of the drilling structure that separates positively flowing drilling mud from drilling mud that is being recirculated. The recirculation action of the fluid in the recirculating loop may be fed and brought about by entrainment of the fluid with jetted fluid from an adjacent nozzle. The portion of the body may form a partition, such as a wall extending at least partially between the sides of the primary channel, a fin positioned within the primary channel that generally radially extends from the centerline of the drilling structure, or an internal channel or feeder that extracts fluid from the annulus at a point of low velocity and reintroduces it at a point of higher velocity proximate the bit face, usually near a nozzle. In addition, portions of the drilling structure are streamlined to further encourage positive, stable flow of fluid and formation cuttings generated from an associated cutting structure.
