| 264 | Spiral ribbed aluminum drillpipe | US12103061 | 2008-04-15 | US07814996B2 | 2010-10-19 | David I. Indrupskiy; Vladimir S. Basovich; Dmitry A. Lubyanyy |
| A spiral ribbed aluminum drillpipe has an intermediate portion with a plurality of ribs spiraling along its length. These ribs have active faces that are exposed by recessed areas. The active faces define incut angles relative to the pipe's outer surface for actively engaging slime/sediment material along a borehole wall. Bearings rotatably disposed on the pipe have a greater diameter than the ribbed intermediate portion or any tool joints on the drillpipe so that the bearings engage the borehole wall. The pipe's body is preferably composed of a lightweight alloy, such as aluminum alloy, whereas the bearings are preferably composed of steel and have wear resistant coating or bands. | ||||||
| 265 | FRICTION REDUCING WEAR BAND AND METHOD OF COUPLING A WEAR BAND TO A TUBULAR | US12755981 | 2010-04-07 | US20100252274A1 | 2010-10-07 | Jean Buytaert; Eugene Edward Miller; Ira Eugene Hining |
| In one embodiment, a wear band comprises a rotating element having a bore receivable on a tubular, the bore comprising first and second bore portions slidably receiving first and second sleeve bearings. Outer surfaces of the sleeve bearings slidably engage the bore portions and the bores of the sleeve bearings slidably engage the tubular. A first and a second stop collars may be received on the tubular to together straddle the rotating element and sleeve bearings to longitudinally secure the rotating element in a position on the tubular. The tubular may be included within a tubular string run into a borehole or into the bore of an installed casing, such as in casing while drilling. The rotating element provides stand-off between a tubular and the wall of a bore, reduces frictional resistance to longitudinal sliding and also to rotation of the tubular string within the bore. | ||||||

| 273 | Vibration-dampening drill collar | US10817870 | 2004-04-06 | US20050217898A1 | 2005-10-06 | Brent Clark |
| A drill collar primarily for use with measurement-while-drilling and logging-while-drilling sensors, the drill collar composed of a non-magnetic nickel alloy, and having three or four elongate nitral elastomer ribs parallel the longitudinal axis and mounted on the inner surface of the drill collar, defining a central aperture for receiving the down-hole sensor and inter-rib apertures for receiving drilling fluid. This novel drill collar is especially useful in rough or underbalanced drilling applications, protecting the sensor and enhancing measurement accuracy by dampening flow-based harmonic vibrations, absorbing vibration from lateral tool movement, and stabilizing/centralizing the sensor within the central aperture. Also, the novel drill collar allows the operator to run lower fluid rates while drilling, minimizing formation damage from fluid invasion. | ||||||

| A well borehole is prevented from deviating from its intended vertical path as it is being drilled by use of a sub assembly which is eccentrically weighted with respect to its axis of rotation. Such a sub assembly can comprise a straight tubular member weight relieved along one side by, for example, forming a cavity within the heavy walls of the tubular member along the side of the collar. Thus, the eccentric weight is imposed upon the drill bit without providing any protrusions or elbows which are designed to bear on the wall of the borehole. Additionally, as the cavity is contained within the heavy walls of the tubular member, drilling fluids containing various debris cannot inhabit the cavity, thus maintaining a constant eccentric weight upon the drill bit. | ||||||

| The present invention provides a drilling assembly and method that is especially useful for a bottom hole drilling assembly for drilling a borehole through an earth formation. In one embodiment, the drilling assembly is preferably comprised of a tungsten alloy which is sufficiently plastic to be able to withstand the bending, torsional, and compressive stresses which occur in a bottom hole drilling assembly. The tungsten alloy weight section may be axially moveable with respect to an outer tubular and when mounted within the bottom hole assembly, acts to place the outer tubular in tension to provide a stiffer bottom hole assembly. | ||||||
