摘要： A hybrid rock bit is disclosed wherein a pair of opposing extended nozzle drag bit legs are positioned adjacent a pair of opposed tungsten carbide roller cones. The extended nozzle face nearest the hole bottom has a multiplicity of diamond inserts mounted therein. The diamond inserts are strategically positioned to remove the ridges between the kerf rows in the hole bottom formed by the inserts in the roller cones.

摘要： A drill bit is disclosed for maintaining a desired direction of drilling or to reduce the deviation already established. The drill bit includes a plurality of legs with each leg having a cone cutter rotatively supported thereon. A plurality of annular rows of cutting inserts are circumferentially mounted on the conical surface of each cutter. Each cone cutter further includes a heel portion adjacent the base of the conical surface. The heel portion is of sufficient mass to support the gage row of cutting elements. The gage row of each cone extends further out from the cone axis than any of the intermediate adjacent rows in such a manner that the annular area of the hole bottom cut by the gage inserts is lower than any other area cut by the intermediate rows of cutting inserts. This extended gage row construction enables the gage inserts to cut into any sloping wall to produce a sharp corner and bring the hole back into line with the drill string. The cutting inserts of each gage row include relatively large cutting faces in the direction of the sidewalls of the bore hole in order to have substantial surface contact with the gage of the bore hole.
摘要翻译：公开了一种用于保持所需钻孔方向或减少已经建立的偏差的钻头。钻头包括多个腿部，每个腿部具有可旋转地支撑在其上的锥形切割器。多个环形排的切削刀片周向地安装在每个刀具的锥形表面上。每个锥形切割器还包括邻近锥形表面的基部的跟部。脚跟部分具有足够的质量以支撑切割元件的量规排。每个锥体的规格行比锥形轴线进一步从任何中间相邻的行延伸出来，使得由量规插入件切割的孔底部的环形区域低于由中间切割行切割的任何其它区域插入。这种扩展的规格行结构使得计量插入件能够切割成任何倾斜的壁以产生尖锐的拐角并使孔返回与钻柱成一直线。每个规格行的切削刀片在钻孔的侧壁的方向上包括相对大的切削面，以便与钻孔的表面具有实质的表面接触。

摘要： A rock bit for drilling hard formations has a bit body with a plurality of rolling cone cutters mounted on it for rotation with rotation of the bit body. The cutters each have a plurality of recesses in their outer surfaces and a tungsten carbide insert is interference fitted into each of said recesses. A large diameter rock bit has such inserts larger than about 3/4 inch diameter and a cavity is provided in the cylindrical base of such an insert. The cavity has a volume in the range of from about 15 to 30% of the volume of the cylindrical base and extends into the cylindrical base a distance of at least about 40% of the diameter of the base. The depth of the recess is more than half of the length of the portion of the insert that grips the recess in which it is inserted. Large savings in expensive tungsten carbide can be made without decreasing performance of the tungsten carbide inserts.

摘要： This concept discloses a new technique which uses brazing or diffusion bonding methods to attach a diamond disk to a wedge-shaped steel support platform on a hybrid type of bit. The invention is primarily concerned with the attachment of the innermost diamond cutting disk on the wedge-shaped drag bit face portion of the hybrid bit. It is particularly difficult to secure any kind of cutting structure to the innermost portion of a rock bit because of the lack of material available to secure the cutting structure to the drag bit face. Space limitations on the drag bit face prevent the use of conventional interference fit diamond insert studs for the innermost cutters.

摘要： A lubrication failure detection system for utilization with an earth boring drilling system having at least one rotary drill bit coupled to a drill string, the drill string having an internal passage adapted to receive drilling fluid under pressure. A lubrication reservoir is disposed near said rotary drill bit and coupled to bearing surfaces within said rotary drill bit by a lubrication passageway. A flexible membrane separates the lubrication reservoir from drilling fluid within the annulus formed by the rotary drill bit and distends inward in response to the pressure of the drilling fluid. The distention of the membrane forces lubricant into the lubrication passageway and when the membrane has distended to a selected point, the membrane actuates a mechanism which opens an orifice into the internal passage of the drill string, thereby abruptly decreasing the pressure of the drilling fluid within the drill string. The system also includes means for detecting this pressure drop, thereby indicating the imminent failure of lubrication within the system. In an alternate embodiment, the system includes means for selectively closing the aforementioned orifice to permit additional operation of the drilling system after imminent lubrication failure has been indicated.
摘要翻译：一种润滑故障检测系统，其用于具有连接到钻柱的至少一个旋转钻头的钻孔钻孔系统，所述钻柱具有适于在压力下接收钻井液的内部通道。润滑储存器设置在所述旋转钻头附近并通过润滑通道联接到所述旋转钻头内的支承表面。柔性膜将润滑容器与由旋转钻头形成的环形空间内的钻井液分离，并响应于钻井液的压力向内扩张。膜的膨胀迫使润滑剂进入润滑通道中，并且当膜已经扩张到选定的位置时，膜致动一种将钻孔打开到钻柱的内部通道中的机构，从而突然降低钻杆液体内的压力钻柱。该系统还包括用于检测该压降的装置，从而指示系统内即将发生的润滑故障。在替代实施例中，该系统包括用于选择性地关闭上述孔口的装置，以便在已经指出了即将发生的润滑故障之后允许钻井系统的附加操作。

摘要： This invention teaches the use of one or more cavitation inducing nozzles in combination with conventional nozzles for rock bits. The cavitation nozzles enhance the drilling rate by rapidly removing cuttings from the hole bottom. Cavitation from a cavitating nozzle positioned on one side of the bit reduces the pressure thereby inducing drilling mud at higher pressure passing through an opposing non-cavitative nozzle to move across the rock-tooth interface. The resultant cross-flow rapidly removes the cuttings from the hole bottom.

摘要： A rock bit with rotary cone cutter means having hardened insert teeth utilizing fewer than the normal number of teeth or of cutters used for a given gage hole wherein the cone cutter body is of greater diameter and for approximately the same axial length, of a greater wall thickness and to accommodate a greater insert tooth depth or grip length and permit a proportional increase in extension of the insert from the cutter body to provide greater penetration with fewer insert teeth in contact at a given time, and also providing for increased journal bearing area to increase the life of the extended insert cutters.

摘要： A rock bit for recovering core samples is described, along with variations for drilling oil wells or the like. In each of these embodiments a plurality of diamond cutters are mounted on the bit body for cutting rock by a shearing action. Each diamond cutter is in the form of a thin diamond plate bonded to a carbide slug that is inserted into the bit body. Means are also provided for limiting the depth of penetration of the diamond cutters into the rock formation being drilled preferably in the form of rolling cone cutters having a plurality of carbide insects protruding from their surfaces. The protrusion of the carbide inserts from the surface of the cutter cones is less than the length of the diamond plate. This limits the depth that the diamond can penetrate in the rock and inhibits damage. Typically the diamond cutters are mounted for cutting one portion of the hole area by shearing action and the rolling cone cutters are mounted for cutting another portion of its area by chipping-crushing action.

摘要： An improved seal assembly for utilization with earth boring drilling bits employing roller cutters. The improved seal is constructed utilizing two resilient O-rings or other resilient seals engaging opposing surfaces in the roller cutter and the corner formed by the shaft and face of the cutter support. The O-rings are mounted in and separated by a flexible floating ring of slightly harder material than the O-ring material. The flexible floating ring may be coated with or made from a material which provides a low coefficient of friction, permitting the O-rings to rotate therein. In an alternate embodiment of the present invention the flexible floating ring is tapered so that increased loading of the earth boring drilling bit will result in increased compression of the resilient O-rings, thus improving the seal under high load conditions. The improved seal of the present invention will accommodate substantial radial, axial and angular displacements of the roller cutter while satisfactorily inhibiting the ingress of detritus and the egress of lubricant.
摘要翻译：一种改进的密封组件，用于利用采用滚刀的钻孔钻头。改进的密封件利用两个弹性O形环或其它弹性密封件构成，该密封件与滚子切割器中的相对表面和由切割器支撑件的轴和面形成的角部相啮合。 O形圈通过比O形圈材料稍稍硬的材料的柔性浮环安装在其中并分开。柔性浮环可以涂覆或由提供低摩擦系数的材料制成，允许O形环在其中旋转。在本发明的替代实施例中，柔性浮环是锥形的，使得钻孔钻头的增加的负载将导致弹性O形环的增加的压缩，从而在高负载条件下改善密封。本发明的改进的密封件将适应滚子切割器的大量径向，轴向和角位移，同时令人满意地抑制碎屑的进入和润滑剂的排出。
