摘要： Electrical generating apparatus is provided which connects to the production tubing. In a preferred embodiment, this apparatus includes a housing having a primary flow passageway in communication with the production tubing. The housing also includes a laterally displaced side passageway communicating with the primary flow passageway such that production fluid passes upwardly towards the surface through the primary and side passageways. A flow diverter may be positioned in the housing to divert a variable amount of production fluid from the production tubing and into the side passageway. In accordance with an important feature of this invention, an electrical generator is located at least partially in or along the side passageway. The electrical generator generates electricity through the interaction of the flowing production fluid.

摘要： A rotation release apparatus is provided for use in a wellbore tool to selectively couple a first wellbore tool member to a second wellbore tool member until the wellbore tool is lowered to a selected depth within the wellbore. The rotation release apparatus includes a coupling member secured to the first wellbore tool member, and a latch member secured to the second wellbore member. A cam member is secured to the coupling member to release the latch member from the coupling member when the wellbore tool is rotated about a longitudinal axis. The rotation release latching apparatus may be operated to couple the latch member to the coupling member by axial movement of the wellbore tool along a longitudinal axis.

摘要： A slip gripping mechanism is shown for supporting a string of cylindrical conduit within the interior bore of a circumscribing well conduit. A cone retaining ring engages a plurality of floating cone segments which define spaced longitudinal slots on the outside of the cylindrical conduit. Vertically shiftable slips are carried in spaced-apart fashion on the cylindrical conduit and have side edges adapted to engage mating profiles formed in the slots. The slots form guideways for the slips for shifting the slips upwardly and outwardly between a set position engaging the circumscribing conduit and an unset position. Selected ones of the slips and cone segments are tapered to index the slips and facilitate alignment within the slots as the slips are brought into contact with the cones during the setting operation.

摘要： A sealing and gripping element for an expandable downhole tool features a ring supporting a sealing material with radially extending rings into the sealing material during run in. Expansion of the underlying ring brings the sealing material into contact with the surrounding tubular. It also forces the radially extending rings through the sealing material and into contact with the surrounding tubular. As a result the tips of the extending rings are blunted to create metal to metal seals on the surrounding tubular. Hardened inserts are also located within the sealing material for run in. Upon expansion of the underlying base ring, the inserts break through the sealing material and penetrate the surrounding tubular to enhance grip when high differential pressures are encountered.

摘要： A one trip system for expanding a tubular that is solid or perforated or a screen comprises a downhole assembly that features a hydraulic anchor that can be set, released and repositioned to repeat the process. The anchor is small enough to go through the tubular or screen after initial expansion. The anchor's maximum extension is designed to avoid overstressing the already expanded tubular or screen. An expansion tool is hydraulically driven with the initial portion of the stroke delivering an enhanced force. The expansion tool initially supports the tubular or liner but subsequently releases during the first stroke, after the tubular or screen is fully supported.

摘要： A compliant swage has the ability to change shape to allow clearance of an obstruction while permitting expansion to go on in other areas removed from the obstruction. A series of segments move with respect to each other longitudinally to change overall size. The segments have an additional degree of freedom to change from a round profile of varying diameter to an oblong, elliptical, or an irregular shape so as to compensate in the portion that encounters an obstruction to let the swage pass while at the same time permitting the intended maximum expansion in other portions where conditions permit such expansion.

摘要： A method of repairing tubulars downhole is described. A swage is secured to a force magnification tool, which is, in turn, supported by an anchor tool. Applied pressure sets the anchor when the swage is properly positioned. The force magnification tool strokes the swage through the collapsed section. The anchor can be released and weight set down on the swage to permit multiple stroking to get through the collapsed area. The swage diameter can be varied.

摘要： A wet connect/disconnect arrangement is disclosed for a downhole system that allows installation of various tools and/or a string and subsequent electrical connection to the downhole system in a wet environment. Several embodiments are disclosed, all of which produce a clean, reliable connection. Exemplary embodiments include an upper section being mechanically and electrically joined to an intermediate section with electrical connectors for being joined at a lower section. The intermediate section further has auxiliary connectors that may be protected by a cover and remain unmated in a first connected application being therefore available for future use. The upper section may be removed leaving the intermediate section in place whereby the unmated connectors are available to rejoin a new upper section. Different types of connectors are also disclosed.

摘要： A wellbore packer and slip combination for production tubing and the like comprises a plurality of slip elements that are caged together around the periphery of a cylindrical mandrel. An axially displaced actuator simultaneously engages all of the elements to ramp one end of all elements against a casing wall. After the one end of the slip and packer unit is set, further displacement of the actuator expands the other end of the elements against the casing wall. The packer and slip assembly may be retracted and recovered by a simultaneous lift and rotation of the tool string.

摘要： The invention relates to actuation of a downhole tool by hydraulic forces in a structure that does not employ lateral openings through the wall of the tool. By a variety of mechanisms, the tool wall is urged to flex preferably within its elastic limits. The wall flexing either signals a sensor which senses such motion to create a corresponding signal which can unlock a piston. Thereafter, hydraulic pressure differences are employed to move the piston to operate the downhole tool.
