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： 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.

摘要： A subterranean drill tool has a seal gland formed between a rotating and a static surface. An annular elastomeric seal is located in the gland in engagement with each of the surfaces. A property gradient is formed in at least part of the elastomeric material. The property gradient defines a property that changes from a first level at the surface to a second level in the interior of the seal. The elastomeric material within the property gradient has the same chemical composition as the rest of the seal.
