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 device and system for improving efficiency of subterranean cutting elements uses a controlled oscillation super imposed on steady drill bit rotation to maintain a selected rock fracture level. In one aspect, a selected oscillation is applied to the cutting element so that at least some of the stress energy stored in an earthen formation is maintained after fracture of the rock is initiated. Thus, this maintained stress energy can thereafter be used for further crack propagation. In one embodiment, an oscillation device positioned adjacent to the drill bit provides the oscillation. A control unit can be used to operate the oscillation device at a selected oscillation. In one arrangement, the control unit performs a frequency sweep to determine an oscillation that optimizes the cutting action of the drill bit and configures the oscillation device accordingly. One or more sensors connected to the control unit measure parameters used in this determination.

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 thread for expandable downhole tubular connections is disclosed. The thread on at least one of the pin and box is coated, preferably with an anti-galling compound. During expansion the coating crumbles and the particles in between the threads keep the joint from becoming undone despite longitudinal shrinkage from the expansion or any tendency of the swage to impart a rotational motion on one part of the joint during the expansion process.

摘要： A downhole completion method and an expandable filtration apparatus are disclosed. The filter assembly comprises a plurality of layers beginning with a coated perforated base pipe. The coating reduces the force required for expansion. A drainage layer overlays the base pipe with the filtration layer above it. The drainage layer improves flow through the filtration layer and protects it from burrs in the base pipe. A filtration enhancement layer fits over the filtration layer and an outer shroud protects the assembly during run in. The assembly can be used as made or expanded downhole in one or a series of expansions.

摘要： A liner hanger assembly has a slip actuation system which is locked for run-in. A piston assembly bolts onto the mandrel in a sealable manner to actuate a mechanical lock. Upon release of the lock, a plurality of springs actuate a sleeve which is in turn attached to the slips to move them relative to their slip seats. The slip seats are preferably mounted to the mandrel without welding and have longitudinal spaces for mud or cement flow therebetween. Load is distributed from each slip through its slip seat into the mandrel without interaction from an adjacent slip or slip seat. A rupture disk ensures that a predetermined pressure is built up before the piston can actuate to defeat the lock. The lock can come in a variety of configurations. One of which is a sliding sleeve over a dog and another is a yoke over a split ring which, when shifted, allows the split ring to expand, thus unlocking the parts. The slips can also be configured to allow flow of mud or cement behind them, thus reducing the resistance to flow of such materials.

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.
