摘要： Catalyst extraction from polycrystalline diamond table may be achieved by treating with a halogen (in the gas phase or dissolved in a nonpolar organic solvent) to convert the catalyzing material to a salt. Then, polar organic solvents may optionally be used to leach the salt from the polycrystalline diamond table. The polycrystalline diamond (with the salt of the catalyzing material present or at least partially leached therefrom) may be brazed to a hard composite substrate to produce a cutter suitable for use in a matrix drill bit.

摘要： A drill bit in which a cutting element support shoe is mounted to a drill bit member so that it covers a portion of a number cutting elements while leaving the cutting edges of cutting elements exposed to the formation. The drill bit member may include a bit body, blade, arm, or roller, for example. The drill bit member may include a recess into which the cutting element support shoe is received. Cutting element support shoe provides mechanical holding of the cutting elements within their pockets in addition to conventional brazing or other mounting techniques. Once installed, a hard facing material may be applied over the cutting element support shoe as appropriate for increased erosion resistance. In one embodiment, the cutting element support shoe is sized so that when mounted to the drill bit member it is elastically deformed, thereby providing additional cutter retaining force upon attachment.

摘要： A reaming bit designed to operate with Sow torque fluctuation when driven with a turbine at speeds in the order of 300-600 RPM and above features a profile that is arcuate from the gauge dimension to the nose area or alternatively has a blunt straight taper section but with a ratio of profile length (PL) to bit size (BS) of under.75. The blades extend into a concave cone and the cutting structure continues along the blades towards the center. The blades have a step near the gauge section to increase the exposure of the blade cutting structure. An array of protrusions are disposed parallel to and behind the cutting structure to increase high speed stability and adjacent the blade step transition to protect outer casing on run in.

摘要： A disclosed method for obtaining a core sample includes directing light at a core sample being collected, receiving reflected light from the core sample, and analyzing the received reflected light to determine one or more characteristics of the core sample and/or form an image of the core sample. Characteristics include rock type, hydrocarbon type, water concentration, porosity, and permeability. The light may be infrared (IR), visible, and/or ultraviolet (UV). The received reflected light may be passed through one or more multivariate optical elements (MOEs). Measurements made at two different positions on the core sample may be used to determine a coring rate. A described coring bit includes a barrel to receive a core sample, a light source illuminating the core sample as it enters the barrel, a detector system that receives reflected light from the core sample, and an optical transmission system communicating light to and from the core sample.
