摘要： A drill bit and method of drilling a subterranean formation are disclosed in which the drill bit is configured with a non-axial gage portion of a bit body. The non-axial gage portion of the bit body presents a peripheral profile which is not parallel to the centerline of the bit body to provide a contact area for engagement of the sidewall of the borehole by at least one cutting element carried by the non-axial gage portion to enlarge the borehole from a first diameter cut by cutting elements on the bit face. The configuration of the drill bit lessens loading on the cutting elements of the drill bit, facilitates maneuverability of the drill bit downhole and enhances steerability of the drill bit.
摘要翻译：公开了钻头和钻孔地层的方法，其中钻头被配置为钻头体的非轴向量具部分。钻头体的非轴向量具部分呈现出不平行于钻头体的中心线的外周轮廓，以提供用于通过至少一个由非轴向承载的切割元件与钻孔的侧壁接合的接触区域通过在钻头面上的切割元件从第一直径切割来扩大钻孔。钻头的构造减轻了钻头的切削元件上的载荷，有利于井下钻头的机动性，并提高了钻头的可操纵性。

摘要： A rotary drag bit including exterior features to control the depth of cut by cutters mounted thereon, so as to control the volume of formation material cut per bit rotation as well as the torque experienced by the bit and an associated bottomhole assembly. The exterior features preferably precede, taken in the direction of bit rotation, cutters with which they are associated, and provide sufficient bearing area so as to support the bit against the bottom of the borehole under weight on bit without exceeding the compressive strength of the formation rock. The exterior features may be oriented and configured to function optimally at a predicted rate of penetration, or range of rates, at which the bit may be operated, such rate or rates being further optionally maximized in softer formations in light of the ability of the bit to hydraulically clear a maximum volume of formation cuttings to prevent so-called bit balling.

摘要： A drill bit for drilling subterranean formations includes a device to provide a "universal" effect between the shank and crown for self alignment of the crown with the bore hole in the formation. The bit is suitable for downhole assemblies configured for straight drilling, directional drilling and navigational drilling. The device can be incorporated into both drag bits and roller-type "rock" bits. Preferred embodiments include a flexible sub connecting the crown to the shank portion and having reduced stiffness relative to the drill string. Alternatively a spherical universal joint or trunnion type universal is used. Replaceable lugs increase durability and reliability of the universal. The device equalizes the loads on cutters while reducing wear, average loads, and impact loads on cutters. Bore hole diameter and chatter of the bit in the bore hole are reduced, promoting maximum efficiency and rate of penetration as wobble and precession are minimized.

摘要： A cutting element having a substantially planar table of superhard material mounted on a substrate or backing. The superhard material table, the substrate, or an insert placed between those two components provides additional stiffness to the cutting element and resistance to bending and impact loading experienced by the cutting element when drilling a formation. The additional stiffness reduces fracture of the table of superhard material and, if the reinforcing member or portion is formed of an abrasion and erosion resistant material, the cutting element will wear linearly at a reduced rate due to the enhanced volume of such material. The thicker or reinforced portion of the cutting element extends linearly, and if the cutting element is circular, extends diametrically. Cooperative arrangements of such cutting elements are also disclosed.

摘要： A drill bit for use with earth drilling equipment, the drill bit having a body and movable cutting members or blades variably positionable between a first position in which the diameter defined by the cutting members is generally equal to or less than the diameter of the drill bit body and a second position in which the diameter defined by the cutting members is greater than the diameter of the drill bit body. The second, expanded position is assumed by the cutting members when they are in contact with the bottom of a hole and are thereby urged upwardly relative to the bit body. The first, retracted position is assumed by the cutting members when the drill bit is being tripped into or out of the hole and, because the cutting members are essentially retracted relative to the bit body, the drill bit does not become jammed downhole. A fixed-blade adaptation of the invention is also contemplated.

摘要： A drag-type drill bit for boring an earth formation having a plurality of cutting elements formed thereon. Each cutting element includes a cutting surface having a cutting edge formed thereon. During boring, the cutting edge is embedded into an earth formation so that the formation is received against a portion of the cutting surface. As the cutting surface advances against the formation, a chip forms. The chip has a first surface directed generally toward the cutting surface and a second surface directed generally in the direction of cutting element travel. A number of different embodiments are disclosed which include means formed on and in the cutting surface for communicating drilling fluid pressure via slots or discontinuities to a location on the cutting surface relatively close to the cutting edge. Drilling fluid pressure across the chip is thus equalized thereby preventing the chip from being urged against the cutting surface due to the difference between the formation pressure and the drilling fluid pressure.
