    摘要: A system for estimating a velocity of a downhole component is disclosed. The system includes: a sensor configured to produce a sensor signal that is proportional to at least one of a position and an acceleration of the downhole component; and a circuit in communication with the sensor and configured to receive the sensor signal and generate an output signal indicative of an instantaneous velocity of the downhole component. A method of estimating a velocity of a downhole component is also disclosed.

    摘要: A roller cone bit having a sealed lubricant reservoir between a roller cone and a head section. A journal sleeve is included on the head section that circumscribes the journal bearing surface of the head section. The sleeve can axially pivot on the head section, but does not rotate thereon. The reservoir is formed into a journal bearing surface of the head section body and may be sealed by placing a seal around its periphery that extends between the journal bearing surface and journal sleeve. Sealing the reservoir results in a hydrostatic condition therein and substantially equalized pressures.

    摘要: A rock bit is formed with pockets for enhanced cutting element retention and support of cutting elements during operation of the rock bit. Portions of the pockets are carburized to increase a yield strength of the pockets, which also increases the retention of the cutting elements. The pockets are formed at a diameter that is slightly smaller than an outer diameter of the cutting elements. Portions of the pockets are then carburized. The pockets are heated until the diameter of the pockets is equal to the outer diameter of the cutting elements. After the rock bit has been cooled and cleaned, a material is placed in each pocket prior to installing the cutting elements. The material homogenizes support for the cutting elements during operation of the rock bit.

    摘要: A drill bit having a bit body includes one or more acoustic sensors that are configured to detect elastic waves when the drill bit is used for drilling a wellbore. The acoustic sensor may be configured to detect a sonic signature associated with a failure event. In further arrangements, the acoustic sensors may be configured to receive signals from a controlled acoustic source.

    摘要: Methods of attaching cutting elements to earth-boring tools, comprising abutting a portion of a cutting element against at least one surface of an earth-boring tool with a braze material disposed therebetween; and brazing the cutting element to the earth-boring tool by applying high-frequency vibrations to cause the braze material to become flowable. Methods of securing cutting elements to earth-boring tools may comprise at least partially coating a cutting element with a braze material. The cutting element may be at least partially disposed in a pocket formed in a body of an earth-boring tool with the braze material adjacent surfaces defining the pocket. The cutting element and the braze material may be ultrasonically torsionally oscillated to braze the cutting element within the pocket.
