    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： An earth-boring rotary drill bit includes a bit body configured to carry one or more cutters for engaging a subterranean earth formation, the bit body comprising a particle-matrix composite material having a plurality of hard particles dispersed throughout a matrix material, the matrix material comprising a shape memory alloy. The matrix material comprises a metal alloy configured to undergo a reversible phase transformation between an austenitic phase and a martensitic phase. The matrix material may include an Ni-based alloy, Cu-based alloy, Co-based alloy, Fe-based alloy or Ti-based alloy. The drill bit may be made by a method that includes: providing a plurality of hard particles in a mold to define a particle precursor of the bit body; infiltrating the particle precursor of the bit body with a molten matrix material comprising a shape memory alloy forming a particle-matrix mixture; and cooling the molten particle-matrix mixture to solidify the matrix material and forming a bit body having a particle-matrix composite material comprising a shape memory alloy.

    摘要： Apparatuses and methods for adjusting weight-on-bit/torque-on-bit sensor bias in a drill bit. The apparatus may include a bit adjustment device disposed at least partially in a cavity in a bit shank. The bit adjustment device includes electronics and sensors for estimating a weight-on-bit/torque-on-bit bias. The method includes adjusting the weight-on-bit/torque-on-bit sensor bias of a drill bit. The method may include adjusting force on a bit adjustment device to adjust weight-on-bit/torque-on-bit sensor bias. The method may also include securing the bit adjustment device within the cavity of the bit shank after the desired weight-on-bit/torque-on-bit sensor bias has been achieved.

    摘要： In one aspect, a method of determining a corrected weight-on-bit is provided, which method, in one embodiment, may include: drilling a wellbore with the drill bit; determining a weight-on-bit while drilling the wellbore; determining a pressure differential across an effective area of the drill bit while drilling the wellbore; and determining the corrected weight-on-bit from the determined weight-on-bit and the determined pressure differential.
