摘要： A bit body formed of a mixture of matrix material and superabrasive powder and including pockets lined with superabrasive-free matrix material, and a method for forming the same, are provided. The pockets are shaped to receive cutting elements therein. The superabrasive-free matrix material enhances braze strength when a cutting element is brazed to surfaces of the pocket. The method for forming the drill bit body includes providing a mold and displacements. The displacements are coated with a mixture of superabrasive free matrix-material and an organic binder. The mold is packed with a mixture of matrix material and superabrasive powder and the arrangement heated to form a solid drill bit body. When the solid bit body is removed from the mold, pockets are formed by the displacements in the bit body and are lined with the layer of superabrasive-free matrix material. The superabrasive material may be diamond, polycrystalline cubic boron nitride, SiC or TiB2 in exemplary embodiments.

摘要： A drill bit for use in a borehole at least partially containing drilling fluid includes a bit body having at least two bit components, including at least one leg, the leg having a journal segment, and a roller cone rotatably mounted upon the journal segment and forming at least one bearing cavity therebetween. Also included is an annular primary seal disposed between the leg and the roller cone, an annular secondary seal disposed between the leg and the roller cone and between the annular primary seal and the borehole and an annular space disposed between the annular primary seal and the annular secondary seal, the annular space at least partially containing fluid and being in substantially absolute fluid isolation from the bearing cavity and a conduit for permitting the flow of fluid from the annular space to the borehole. The annular secondary seal may be primarily elastomeric and a passage for permitting the flow of fluid may further permit the flow of fluid from the borehole to the annular space. The annular space may at least partially include a grease possessing a water washout value of under approximately 50% per ASTM D-4049 water spray test for lubrication characteristics and the grease may include a polymer tackifier of between approximately 1% and approximately 5% by weight.

摘要： A rotary cone bit, having a functionally-engineered surface of this invention, comprises a bit body having at least one leg extending therefrom, and a cone that is rotatably disposed on the leg. The cone typically comprises a plurality of cutting elements that project outwardly therefrom. The cutting elements comprises a cermet material selected from the group consisting of refractory metal carbides, nitrides, borides, carbonitrides and mixtures thereof. A functionally-engineered material is disposed over a surface portion of at least one of the cutting elements to form a wear resistant surface thereon. The wear resistant surface has a hardness that is different than that of the underlying cutting element. The wear resistant surface is provided by forming a conformable material mixture by combining one or more powders selected from the group consisting of cermets, carbides, borides, nitrides, carbonitrides, refractory metals, Co, Fe, Ni, and combinations thereof, with an applying agent. The applied material mixture is pressurized under conditions of elevated temperature to consolidate and sinter the material mixture, thereby forming the wear resistant surface. The material mixture is consolidated and sintered in a manner that avoids unwanted material migration between the applied material mixture and substrate, thereby providing a fully-densified wear surface having desired properties of hardness and/or fracture toughness.

摘要： An improved O-ring seal for rock bit bearings comprises a body formed from a resilient elastomeric composition and a modified surface comprising a surface enhancing material integral with the body. The surface comprises a layer of surface enhancing material that encapsulates and is molecularly bonded to an underlying surface of an elastomeric seal body. The surface enhancing material selected may include metal disulfides, fluoropolymers, ethylene polymers, silicone polymers, and urethane polymers. The O-ring surface displays enhanced properties of reduced break-off friction, increased lubricity and wettablity, and increased thermal resistance. These enhanced surface properties serve to minimize stick-slip and material loss from the O-ring surface resulting from stick-slip, thereby increasing the service life of the O-ring seal and rock bit.
摘要翻译：用于岩石钻头轴承的改进的O形密封件包括由弹性弹性体组合物形成的主体和包括与主体成一体的表面增强材料的改性表面。表面包括一层表面增强材料，其包封并分子结合到弹性体密封体的下表面。选择的表面增强材料可以包括金属二硫化物，含氟聚合物，乙烯聚合物，硅氧烷聚合物和聚氨酯聚合物。 O形圈表面显示出降低的断裂摩擦，增加的润滑性和润湿性以及增加的耐热性的增强性能。这些增强的表面性能用于最大限度地减少由于粘滑而导致的O型圈表面的粘滑和材料损失，从而增加了O型圈密封和岩石钻头的使用寿命。

摘要： Methods and systems for recovery of natural gas liquids (NGL) and a pressurized methane-rich sales gas from liquefied natural gas (LNG) are disclosed. In certain embodiments, LNG passes through a heat exchanger, thereby heating and vaporizing at least a portion of the LNG. The partially vaporized LNG passes to a fractionation column where a liquid stream enriched with ethane plus and a methane-rich vapor stream are withdrawn. The withdrawn methane-rich vapor stream passes through the heat exchanger to condense the vapor and produce a two phase stream, which is separated in a separator into at least a methane-rich liquid portion and a methane-rich gas portion. A pump pressurizes the methane-rich liquid portion prior to vaporization and delivery to a pipeline. The methane-rich gas portion may be compressed and combined with the vaporized methane-rich liquid portion or used as plant site fuel.
