摘要： Reamers for use in core-sample drilling having PDC inserts and methods for using the reamers with PDC inserts are described. A reamer with PDC inserts may be used to maintain borehole diameters, reduce deviation, and/or stabilize drill strings used in core sample drilling. The PDC inserts may be of different sizes and shapes and may be arranged around the reamer in various ways.

摘要： Impregnated drilling tools include elongated structures that provide enhanced properties. The drilling tools contain a diamond-impregnated cutting section that contains elongated structures made from carbon, glass, ceramic, and the like. The elongated structures can comprise tubes, fibers, or rods. In one or more implementations the elongated structures are nano-sized. The elongated structures can control the tensile strength and/or the erosion rate of the drilling tools to optimize the cutting performance of the tools. Additionally, the elongated structures may also weaken the cutting section in one or more implementations; thereby, allowing higher strength binders to be used. Such higher modulus binders can cost less and allow for tailoring of the cutting section to retain the diamonds for the desired amount of time. As the cutting section erodes, the elongated structures may also increase the lubricity at the face of the cutting section.

摘要： A drill head assembly includes a shaft having a shaft axis, an oscillator assembly operatively associated with the shaft, the oscillator assembly having at least one eccentrically weighted rotor configured to rotate about a pivot point to generate an oscillating vibratory force, wherein an oscillation centerline is defined transverse to the shaft axis and including the pivot point. The drill head assembly also includes a lower bearing coupled to the shaft on a first side of the oscillation centerline and an upper bearing coupled to the shaft on a second side of the oscillation centerline, the second side being opposite the first side.

摘要： Fibers for diamond-impregnated cutting toois and their associated methods for manufacture and use are described. A matrix is formed that contains fibers made from carbon, glass, ceramic, polymer, and the like. The matrix is then sintered to form a cutting portion of a drill bit. The type and concentration of the fibers can be modified to control the tensile strength and the erosion rate of the matrix to optimize the cutting performance of the tools. Additionally, the fibers may be added to the cutting section to weaken the structure and allow higher modulus binders to be used for the cutting tools at a lower cost, allowing the amount of fibers to be tailored to retain the diamonds in the cutting portion for the desired amount. As the cutting portion erodes, the fibers may also increase the lubricity at me face of the cutting portion.
摘要翻译：描述了用于金刚石浸渍切割的纤维及其相关的制造和使用方法。形成包含由碳，玻璃，陶瓷，聚合物等制成的纤维的基体。然后将基质烧结以形成钻头的切割部分。可以改变纤维的类型和浓度，以控制基质的拉伸强度和侵蚀速度，以优化刀具的切割性能。此外，可以将纤维添加到切割部分以削弱结构，并允许以更低的成本将较高模量的粘合剂用于切削工具，从而允许定制纤维量以将金刚石保留在切割部分中用于所需数量。当切割部分侵蚀时，纤维也可以增加切割部分的表面处的润滑性。
