摘要： An axial bearing is designed to work in a liner hangar in which radial package space is at a premium. Rollers axially separate two washers. To hold the bearing together prior to installation, a sleeve radially surrounds the rollers and has tabs which fit into circumferential grooves in the washers. The sleeve may be metal or plastic.

摘要： Service life characteristics of an elastomer component used for sealing in a BOP are monitored. Measurements are made in situ on the BOP while deployed at a wellsite. The measurements can be related to contact pressure and/or sealing pressure of elastomer components in an annular BOP. The measurements are used to monitor the service life of the elastomer component. The service life can also be estimated using one pressure sensor below the elastomer seal or two pressure sensors positioned above and below the elastomer seal. The pressure variations below the elastomer are monitored versus piston position and used to detect elastomer wear with time/ pressure cycles. The pressure variations above the elastomer can be used to detect potential leakage, as well as leak characteristics such as leaking rate or leak geometry.

摘要： A downhole motor-pump assembly disposed within a tubular string includes a rotor and a stator. The rotor has a first rotor portion and a second rotor portion. The first rotor portion has a first geometrical shape and the second rotor portion has a second geometrical shape. The first geometrical shape differs from the second geometrical shape. The stator has a first stator section and a second stator section. The first stator section is spaced from the second stator section by a gapped region. The first rotor portion is located within the first stator section and the second rotor potion is located within the second stator section. The differing geometry causes a difference in displacement in the first and second sections per revolution of the rotor. Therefore the difference in displacement must be made up and is induced into the tool at the gap or drillings between sections, and this additional volume is effectively pumped.
摘要翻译：布置在管柱内的井下马达 - 泵组件包括转子和定子。转子具有第一转子部分和第二转子部分。第一转子部分具有第一几何形状并且第二转子部分具有第二几何形状。第一个几何形状不同于第二个几何形状。定子具有第一定子部分和第二定子部分。第一定子部分与第二定子部分隔开间隙区域。第一转子部分位于第一定子部分内并且第二转子部分位于第二定子部分内。不同的几何形状导致转子每次旋转时第一和第二部分的位移差异。因此，必须补偿位移差异，并在间隙处或工具间钻孔时将其引入到工具中，并且这个额外体积被有效泵送。

摘要： A drive system housing is provided with an engagement-disengagement mechanism that is advantageous to connect (make up) or disconnect (break out) drill bit or other device connection from the drive system housing. The drive system housing comprises: an upper housing and a lower housing connected thereto by a threaded connection provided at a first end of the lower housing, wherein the upper and the lower housing define an axis; and a plurality of castellations projecting substantially axially from a second end of the lower housing and circumferentially spaced around the axis, wherein at least partially unscrewing the threaded connection is configured to cause axial displacement of the lower housing towards a drive shaft which is coaxially positioned within the upper and the lower housing,and wherein the axial displacement of the lower housing towards the drive shaft is configured to compel the castellations of the lower housing into mating engagement with complementary castellations provided at the drive shaft.

摘要： A clamping assembly may include a split-ring device and bearing for coupling to a driveshaft. The split-ring device may comprise split-ring shells having protrusions on an interior radial surface for positioning in grooves adjacent to radial protrusions on the driveshaft. In some aspects, the split-ring shells may include tabs corresponding to cavities on a first bearing for coupling the split-ring shell to the first bearing. In other aspects, the split-ring shells may be sized to create one or more gaps when positioned on the driveshaft. The first bearing may include one or more corresponding tabs for positioning in the one or more gaps created by the split-ring shells. A second bearing may be threadably coupled to the first bearing to suppress the axial and rotational movement of the clamping assembly separate from the driveshaft.
