摘要： Polycrystalline ultra-hard constructions are made by subjecting a sintered ultra-hard body, substantially free of a sintering catalyst material, to a further HPHT process. The process is controlled to initially melt and infiltrating a filler material into the sintered ultra-hard body to form a filler region having interstitial regions filled with the filler material. The filler region extends a partial depth into the sintered ultra-hard body and is formed at a temperature below the melting temperature of an infiltrant material. Next, the process is controlled to melt and infiltrate the infiltrant material into the sintered ultra-hard body to form an infiltrant region that extends a partial depth into the sintered ultra-hard body. A portion of the filler region and/or the infiltrant region may be removed to form a thermally stable region.

摘要： A method for making dynamic borehole azimuth measurements while drilling includes processing cross-axial magnetic field measurements in combination with accelerometer measurements to compute the dynamic borehole azimuth. In one or more embodiments, the cross-axial magnetic field measurements and the accelerometer measurements may be used to compute the magnitude of a cross-axial magnetic field component, a toolface offset, and a borehole inclination, which may in turn be used to compute the dynamic borehole azimuth. The disclosed methods may utilize near-bit sensor measurements obtained while drilling, thereby enabling a near-bit dynamic borehole azimuth to be computed while drilling.
