摘要： Downhole tool bearings are provided with diamond-enhanced materials. The diamond-enhanced materials comprise diamond grains in a matrix of tungsten or silicon carbide or a silicon-bonded diamond material. A brazed diamond grit or diamond particles coated with a reactive braze may be utilized for bearing applications. Bearing rings for use in downhole tools may be formed at least in part with the diamond-enhanced material. In one embodiment, the bearing rings may be used in a positive displacement motor. In additional embodiments, the bearing rings may be used in a submersible pump.

摘要： Se proporcionan cojinetes de herramienta del fondo de la perforación con materiales mejorados con diamantes. Los materiales mejorados con diamantes comprenden granos de diamante en una matriz de tungsteno o carburo de silicio o un material de diamante enlazado con silicio. Granalla de diamante o partículas de diamante cobre-soldadas revestidas con cobre-soldadura reactiva pueden utilizarse para aplicaciones de cojinete. Anillos de cojinete para su uso en herramientas del fondo de la perforación pueden formarse por lo menos en parte con el material mejorado con diamante. En una modalidad, los anillos de cojinete pueden utilizarse en un motor de desplazamiento positivo. En modalidades adicionales, los anillos de cojinete pueden utilizarse en una bomba sumergible.

摘要： A backup ring for a face seal in a roller cone bit is configured to resist wear from drilling fluids present adjacent exposed faces of the backup ring. Portions are removed from an exposed end face in a variety of shapes while the hardness of the material is increased. The removal of material offsets an increase in force that would be transmitted through the backup ring on face seal assembly due to flexing. A spring can optionally be included in the removed material location. Another way is to increase the edge density of all or part of the exposed edges while leaving the interior portions unaffected by using electron beam radiation to increase the crosslink density or by other techniques that allow a unitary structure with a more durable edge region.

摘要翻译：用于辊锥形钻头中的面密封件的支撑环被配置为抵抗来自邻近的支撑环的暴露表面的钻井液的磨损，部分以各种形状从暴露的端面移除，同时材料的硬度增加。材料的去除抵消了由于弯曲而将在面密封组件上通过支撑环传递的力的增加。可以可选地在去除的材料位置中包括弹簧。另一种方法是增加所有或部分暴露边缘的边缘密度，同时通过使用电子束辐射不影响内部部分以增加交联密度，或通过允许具有更持久的边缘区域的整体结构的其它技术来增加边缘密度。

摘要： A roller cone bit is provided that includes a wear resistant diamond-like carbon coating applied to a bearing shaft, where it is in sliding contact with the bearing seal. The wear resistant diamond-like carbon coating reduces wear and corrosion of the head bearing shaft sealing surface and provides extended life to the bearing seal.

摘要： Un método para lubricar un sistema de soporte adiamantado de una herramienta de fondo de perforación para pozos implica distribuir un lubricante de poliol para la reducción de fricción entre las dos superficies adiamantadas. El lubricante forma una película superficial de fricción reducida sobre el diamante. El lubricante de poliol puede mezclarse con agua. El lubricante de poliol puede contener etilenglicol, glicerol, o una combinación con agua.
