摘要： A nozzle retention receptacle for rotary cone rock bits consists of a nozzle retention receptacle body forming a fluid passage therethrough. The body forms a first upstream entrance end that forms part of a wall of a plenum formed within a rock bit body and a second downstream exit end. The upstream end further forms a mounting interface that circumvents a fluid entrance port to the passage in the nozzle retention receptacle. The port communicates with the fluid plenum in the bit body. The body of the rock bit further forms a nozzle retention receptacle mounting interface that is common to the mounting interface formed by the nozzle retention receptacle.

摘要： Ordered elastomeric composites comprise an ordered arrangement of a number of first elastomeric phases distributed uniformly within a continuous matrix second elastomeric phase. The second phase can be formed from an elastomeric material that is relatively harder than an elastomeric material that is used to form the first phases. Each first phase can be in the form of a core having a defined length and diameter, and the second phase can be formed from a number of shells that each surround a respective core. In a preferred embodiment, the arrangement of cores and shells are aligned coaxially with one another to provide a cellular structure. Ordered elastomeric composites of this invention can be used to form part of or an entire elastomeric seal, e.g., in the form of an annular ring adapted for use in a rotary cone drill bit.

摘要： A roller cone drill bit is disclosed which includes a bit body adapted to be coupled to a drill string. A bearing journal depends from the bit body. A single roller cone is rotatably attached to the bearing journal. The roller cone has a plurality of inserts disposed at selected positions about the cone. The journal defines a rotation angle with respect to an axis of rotation of the bit such that the roller cone includes a wall contact zone and a bottom contact zone. At least one of the inserts disposed in the wall contact zone has an extension portion terminating in a substantially planar upper surface.

摘要： A nozzle and retainer assembly is provided for use in a rotary cone earth boring bit that allows for a larger internal passage in the nozzle. In one aspect, the assembly has a nozzle seated on a shoulder in a receptacle with a stepped portion extending radially outward with a first nozzle shoulder spaced from and facing toward the shoulder in the receptacle to partially define a seal gland. The stepped portion has a second nozzle shoulder facing toward the open end of the receptacle and the retainer engages the inside surface of the receptacle and the second nozzle shoulder to retain the nozzle in the receptacle.

摘要： A composite mini-extended nozzle is disclosed that is designed to both resist erosion and be strong enough to withstand the shock of a downhole drilling environment. In addition, means are provided to shroud at least a portion of the extended nozzle to further protect a portion of the nozzle nearest the exit plane from downhole obstructions. A combination of materials used to form the nozzle may include a matrix of tungsten carbides with suitable binder joined to an outer metal jacket nozzle body. A third ceramic matrix material may be utilized to line or partially line an interior passage formed by the mini-extended nozzle and a reduced in diameter portion of the nozzle design may include a built-in fracture plane in the unlikely event the end of the nozzle hits an obstruction. The extended portion of the nozzle will shear off along this fracture plane thereby preventing a nozzle washout that likely would result in a trip out of the hole to repair the resultant damage to the rock bit.
摘要翻译：公开了一种复合微型延伸喷嘴，其设计成既可以抵抗侵蚀，又能够承受井下钻井环境的冲击。此外，提供了用于遮盖延伸喷嘴的至少一部分的装置，以进一步保护最靠近出口平面的喷嘴的一部分不受井下障碍物的影响。用于形成喷嘴的材料的组合可以包括具有与外部金属护套喷嘴体接合的合适粘合剂的碳化钨基体。可以使用第三陶瓷基质材料将由微型扩展喷嘴形成的内部通道排列或部分排列，并且喷嘴设计的减小的直径部分可以包括在不太可能的情况下喷嘴端部的内置断裂平面遇到障碍喷嘴的延伸部分将沿着该断裂平面剪切，从而防止可能导致从孔中脱出的喷嘴冲洗，以修复对钻石钻头造成的损坏。

摘要： A rotary cone rock bit for drilling boreholes in an earthen formation is disclosed. One or more rotary cones are rotatively retained on a journal bearing connected to the rock bit. These rotary cones form a circumferential heel row with extended ultra hard shaped cutters spaced within the heel row. Each of the shaped cutters form a cutting surface that extends above the heel row or is angled with respect to the formation to maintain the cutters in compression while the cutters shear a borehole wall. The shaped cutters serve to maintain the borehole diameter.

摘要： A rotary cone rock bit for drilling boreholes in an earthen formation is disclosed. One or more rotary cones are rotatively retained on a journal bearing connected to the rock bit. These rotary cones form a circumferential heel row with extended ultra hard shaped cutters spaced within the heel row. Each of the shaped cutters form cutting edges that shear a borehole wall formed by the formation as the rotary cone rotates against a bottom of the borehole formed by the formation. The shaped cutters serve to maintain the borehole diameter and to divert formation debris away from bearing surfaces formed between the rotary cone and the journal bearing.

摘要： A chisel insert for rolling cone rock bits is disclosed in which the crest of the insert has a "dog bone" shape by being rounded with the crest ends flaring out to a larger dimension than the middle thereof. The crest is also convex upwardly along its median line thereby making a shorter moment arm at the ends of the crest.
