    摘要： A straight bore metal-to-metal seal for connecting a tubing string to the mandrel of a well packer has a radially deflectable sealing member compressed between the internal bore surface of a tubular seal receptacle and the tubular body portion of a seal mandrel. The seal receptacle has a radially stepped sealing surface which is engaged by the deflectable sealing member in the operative sealing position. The inside bore of the deflectable sealing member is positively sealed against the outside surface of the seal mandrel by a pair of metal V-rings. A positive seal is also produced by engagement of the deflectable sealing member against the radially stepped bore of the seal receptacle. The deflectable sealing member is loaded by radial compression forces produced as a result of interference engagement of the deflectable sealing member against the radially stepped bore.

    摘要： In a retrievable packer adapted for service under high temperature and high pressure operating conditions, improved sealing is provided by a seal element prop surface which is radially offset with respect to the seal element support surface of the packer body mandrel. At least one seal element is supported on the elevated prop surface and is subjected to a radial squeeze in the set configuration, even though the lowermost outside seal element may be subject to longitudinal separation. The split level seal element support arrangement provides an annular pocket into which the seal elements can be retracted upon release and retrieval of the packer, thereby providing clearance for unobstructed retrieval. Upon release of the packer, a retainer collar is shifted away from a metal backup shoe, thereby providing an annular pocket into which the metal backup shoe is deflected, so that it does not obstruct the drift clearance as the packer is retrieved. The upper outside seal element is reinforced by a garter spring assembly having deformation resistant reinforcing material enclosed within a helical wound coil. Preloading of the seal element assembly is provided by a cover sleeve which releases when a predetermined amount of compression has been achieved. The controlled preloading of the seal elements assists movement of the elements from the lower O.D. of the packer mandrel to the upper O.D. of the prop surface, and the seal elements are forced to expand into the annulus uniformly for preventing the formation of uneven extrusion gaps.

    摘要： Disclosed herein are methods and apparatus for releasing a releasable packer. The apparatus may include shear screws, a mechanism for isolating the shear screw from a shearing force. The mechanism for isolating the shear screw from a shearing force is selectively unlockable to expose the shear screw to the shearing force. The methods may include unlocking a mechanism protecting at least one shear screw, applying a shearing force to the at least one shear screw, and shearing the at least one shear screw.

    摘要： A transmission is provided having a dual clutch, to achieve torque flow through a countershaft gearing arrangement. The countershaft gearing arrangement includes a plurality of co-planar gear sets having gears that are selectively connectable to a first and second countershaft. A transfer gear set transfers torque from the countershaft to an output shaft. The output shaft is connected to a final drive unit that has a final drive unit output shaft that is transverse to an input member connected at one end to a torque converter and at the other end to the dual clutch.

    摘要： A computer-implemented method for managing participants of a marketing campaign is disclosed. The method includes generating a marketing campaign with multiple tracks. Each track comprises one or more steps that indicate an activity executed on campaign participants. The method also includes generating segmentation conditions based on natural language statements. Each segmentation condition includes a rule and a time condition. Additionally, the method includes associating a campaign participant from a first track to a second track if behavior information satisfies a segmentation condition. The behavior information includes a response by the campaign participant to an activity indicated by a step in the first track.
