摘要： A system for forming a patch in a well at a location along a tubular string which has lost sealing integrity includes a central patch body 60, an upper expander body 52 carrying an upper seal 50 or 56, and a lower expander body 98 carrying a lower seal 102, 104. The running tool includes an inner mandrel 14 axially moveable relative to the central patch body, and one or more pistons 20, 30, 20A axially moveable relative to the inner mandrel in response to fluid pressure within the running tool. Top expander 48 is axially moveable downward relative to the upper expander body in response to movement of the one or more pistons, and a bottom expander 120 is axially moveable upward relative to a lower expander body. After the upper expander body and a lower expander body have been moved radially outward into sealing engagement with a downhole tubular string, the running tool is retrieved to the surface.

摘要： The liner hanger running tool 120 includes improvements to the running tool release mechanism, the packoff bushing, and the packer setting assembly. The release mechanism may be operated hydraulically in response to fluid pressure, although the tool may also be released mechanically by right-hand rotation of the running string. The releasing mechanism includes inner piston 340, an outer piston 342, and a clutch 316. The packoff bushing 10 includes a C-shaped lock ring 36 which allows the packoff bushing to be repeatedly restabbed into the top of the liner hanger. The packer setting assembly 52 includes a C-shaped ring 64 for applying set-down weight to a setting sleeve, with pressure assist provided by seals for engaging the mandrel 132 and the setting sleeve 90. A method is provided for reliably releasing a running tool from a liner hanger, for allowing stabbing of the running tool packoff bushing into the top of the liner hanger, and for reliably setting the radial set packer element.

摘要： A cavity positioning tool includes a housing adapted to be coupled to a downhole string. The cavity positioning tool includes at least one blunt arm pivotally coupled to the housing. Each blunt arm is configured to contact a surface of the cavity to position the tool in the cavity. The cavity positioning tool also includes a piston slidably disposed within the housing. The piston is operable to engage each blunt arm. The piston is also operable to receive an axial force operable to slide the piston relative to the housing. The sliding of the piston extends each blunt arm radially outward relative to the housing from a retracted position.

摘要： A downhole tool for use in a wellbore, comprises a tubular member, such as a drill collar housing, in a drill string. The tubular member has at least one cavity formed on an external surface. At least one housing is adapted to be insertable and extractable in the cavity without further tool disassembly. The housing has at least one electrical device such as a battery stack disposed within. In another aspect, sensors are disposed in the housing for measuring downhole parameters of interest including, but not limited to, annulus pressure and annulus temperature. A method of replacing an electrical device in a downhole tool, comprises removing a first housing containing the electrical device from a cavity on an external surface of the downhole tool, and installing a second housing containing a second electrical device in the cavity without disassembling the tool further.

摘要： An apparatus and method for forming a wellbore casing. An annular piston is displaced in the axial direction by pressurizing an annular piston chamber. The axial displacement of the piston radially expands a tubular member into contact with a preexisting tubular member. The radially expanded liner hanger is then decoupled from the apparatus.

摘要： An improved downhole tool apparatus for limiting the extrusion of a packer element. The apparatus includes a packer mandrel having a packer element assembly disposed in a wellbore. Packer retaining shoes are disposed about the packer mandrel at the ends of the packer element assembly. The packer retaining shoes have an inner retainer and an outer retainer. The inner retainer has a plurality of segments having gaps therebetween that expand in width when the retaining shoe is moved from an initial position in which it is disposed about the packer mandrel to an expanded position wherein it engages the wellbore to limit the extrusion of the packer element assembly. The outer retainer is likewise made up of a plurality of segments having gaps therebetween that will expand. The outer retainer engages the wellbore to limit the extrusion of the packer element assembly. The inner retainer segments cover the gaps that exist between the outer retainer segments and the outer retainer segments cover the gaps that exist between the inner retainer segments so that extrusion is limited. The packer retaining shoes also include a wedge disposed about the packer mandrel at the upper and lower ends of the packer element assembly. The retaining shoes provide enhanced high temperature and higher pressure performance in that extrusion in wells having high temperature and high pressure is severely limited if not completely prevented.

摘要： A retrievable hydraulically operated running tool 10, 50 is run in a wellbore to preform a desired downhole tool activation. The port closure member 14, 52 is movable with a tubular body 12 from a port isolation position to an open port position. A seat 18, 56 supported on the port closure member receives a plug to shift the port closure member to the open port position, wherein the port 32, 56 exposes increased fluid pressure to the piston 24, 58, 70 to move to an activated position. The seat may be deformable for release in the plug from the seat after the port closure member has moved the open port position.

摘要： A clamp for clamping two concentric tubes, typically two concentric tubes in an oil or gas well. The clamp has two axially movable tapered components which can be pulled over one another in an axial direction to provide a contraction of internal diameter which grips the smaller diameter tube. In one embodiment, a spacer is fitted to allow the tapered components to be held apart until the tubes have been correctly positioned. The spacer is then removed, and the tapered components are drawn together to effect the clamping. A hydraulic ram can be provided to separate the tapered components should readjustment be required. In another embodiment, the larger diameter tube is made with a relatively thin wall, so that it can be distorted inwards to grip the smaller tube.

摘要： A tool for running and retrieving a whipstock in a subterranean wellbore includes a tool body that has one end that is adapted to be connected to a pipe. The tool body includes a rail defined thereon that is adapted to selectively engage a slot defined on the whipstock. The pipe is in fluid communication with a bore defined in the tool body. The tool body includes a latch assembly for releasably connecting to the whipstock. The latch assembly is adapted to be moved when pressure is applied to the tool bore through the pipe thereby enabling the connection and disconnection of the latch assembly from the whipstock.

摘要： A subterranean cavity positioning system includes a down-hole device and a cavity positioning device rotatably coupled to a well portion of the down-hole device. The cavity positioning device includes a counterbalance portion operable to automatically rotate the cavity positioning device from a retracted position to an extended position as the cavity positioning device transitions from a well bore into the subterranean cavity. The counterbalance portion is also operable to align the cavity positioning device with the well bore as the down-hole device is withdrawn from the subterranean cavity.
