摘要： A packer for use in a wellbore includes a packer mandrel. First and second pistons are slidably disposed about the packer mandrel defining first and second chambers therewith. An activation assembly initially prevents movement of the first piston. A release assembly initially prevents movement of the second piston. First and second seal assemblies are disposed about the packer mandrel such that actuation of the activation assembly allows a force generated by a pressure difference between the wellbore and the first chamber to shift the first piston in a first direction toward the first seal assembly to radially expand the first seal assembly and to actuate the release assembly and, actuation of the release assembly allows a force generated by a pressure difference between the wellbore and the second chamber to shift the second piston in the first direction toward the second seal assembly to radially expand the second seal assembly.

摘要： A downhole tool for providing a seal downhole within a wellbore for reducing loading experienced by a sealing member of the downhole tool is disclosed. The downhole tool may include a pair of directional locking members, at least one of which is operable to transfer a loading experienced by the downhole tool through rigid components of the downhole tool, thereby bypassing the sealing member.

摘要： A metal-to-metal seal assembly which provides a dynamic seal between two moving members yet does not require constant compressive loading. A hollow seal ring is provided having a "C"-shaped cross section and containing a coiled spring. The seal ring is disposed between two telescoped members of an expansion joint, or polished bore receptacle, in an interference fit and is flanked by two bearing rings. The seal ring is located relative to the pressurized fluid so that the fluid pressure is equalized across the ring and remains constant between the two telescoped members despite relative movement therebetween.

摘要： An apparatus for actuating a downhole tool within a well bore comprises a cylindrical mandrel extending longitudinally through the downhole tool; an interventionless, hydrostatic, top-down actuating piston disposed about the mandrel and forming a first chamber and a second chamber therebetween; and a rupture disk that prevents fluid communication between the well bore and the first chamber until sufficient hydrostatic pressure is applied to the well bore to fail the rupture disk.A method of actuating a downhole tool comprises connecting a top-down actuating module to the downhole tool, running the downhole tool to a desired depth within a well bore, pressuring up the well bore without pressuring up an internal flow bore extending through the top-down actuating module, hydrostatically actuating an upper piston of the top-down actuating module to exert an actuation force onto the downhole tool, and actuating the downhole tool.
