摘要： A valve is mounted to a tubular string and has an actuation assembly that is isolated from well fluids. The valve member can be a ball that rotates on a pivot and is actuated by relative rotation of string components that straddle the ball. Rotation of one string component is linked to the closure ball by an external slanted slot with an operating ball that rides in it and connects the rotating string component to the closure ball. Travel stops limit the desired rotation of the closure ball in opposed directions. The closure ball can alternatively be rotated by relative longitudinal string component movement that is converted to relative rotation such as through the use of a j-slot mechanism. Internal seals isolate the slanted slot and operating ball from well fluids.

摘要： A control or other line with a hole downhole can be repaired by pumping a device that is driven by pressure delivered behind a leading seal. The device advances until the leading seal passes the opening in the line where its forward movement is stopped. Upstream of the opening a fluid activated seal is energized so that seals now straddle the opening in the wall. A passage that extends between the seals is opened by blowing a rupture disc with internal pressure to once again give access to the downhole tool through the passage that has external seals to straddle the hole in the tubing wall. Normal operation of the downhole tool can then resume.

摘要： A cutting assembly for external conduits on a tubing string features a breakaway in the string that can be severed with a tensile force. Preferably each external conduit is run through a cutter housing. Upon severing of the string and applying a pickup force, a tension is applied to each external conduit since the severing of the string happens above all the cutter housings. Each housing cuts at least one conduit and the upper portion of the string brings with it the upper portion of the external conduit while the lower portions of each cut external conduit are retained in the cutter housings that remain downhole below the breakaway. In that manner there are no loose external conduit ends to interfere with and/or disturb subsequent fishing or other wellbore operations.

摘要： A spring for use in downhole tools delivers a high force over a long deflection in a relatively uniform fashion. The spring is a tubular shape that is preferably metallic and is preferably plastically deformed into an undulating walled tube either before assembly into a downhole tool or downhole after assembly to the downhole tool. Alternatively the shape can be machined. Spacer rings are used inside and outside the tube as it is compressed to obtain the desired corrugated wall pattern and to prevent localized buckling that can cause wall failure. The spring can conduct pressurized fluids and be rotationally locked to transmit torque and to facilitate milling out. Some machining internally and/or externally can assist in forming the desired corrugated wall shape.

摘要： A swelling packer is covered with a material that is preferably in a tubular form and slipped over the swelling element to be shrink fit with applied heat. The material is formulated to break down at temperatures slightly below the expected downhole temperatures so that ideally the packer has about 48 hours of swelling delay which is normally a time period long enough to allow it to be properly located without it swelling so much as to cause it to be damaged by running in. Various polymers can be used to make an imperious covering for run in that on the way starts to break down. Ideally the material for the cover disappears about the time of sealing or shortly thereafter.

摘要： A milling assembly can be delivered downhole on wireline. Once at the desired location, a processor extends centralizing and driving wheels to initially position the assembly. The assembly has a cutter end with one or more mills or cutters that can be selectively radially extended. The entire cutter end can be rotated in an arcuate manner over a predetermined range. One or more cutter can be extended at a time and driven. The wheels are driven either in an uphole or downhole direction at the same time the arcuate motion can take place. Using a processor, different shapes in a surrounding tubular can be made such as windows for laterals, a plurality of openings for production or interior locator surfaces to properly position subsequent equipment with respect to openings already made by the device.

摘要： A method of centralizing tubulars prior to cementing and subsequent expansion involves using a plurality of telescoping cylinders whose leading or trailing end is closed and which are extended by applied internal pressure in the tubular or some mechanical means. The tubular is expanded from its interior with the cylindrical telescoping members still extended. The cement is pushed all around the tubular due to the centralizers. After the cement is delivered the expansion of the tubular pushes the telescoping members into the borehole wall.

摘要： A wellbore cleanup tool collects debris when moved in one direction downhole. A flow diverter is extended for such flow diversion when debris is collected. When running the tool in the opposite direction in the wellbore, the flow diverter is in whole or in part articulated to retract so as to reduce resistance to fluid that passes around the outside of the tool. A segmented diverter can have fixed and movable components that are guided. The movable components can become longitudinally offset from the fixed components for movement in the direction where maximum flow bypass around the outside of the tool is desired. In an alternative embodiment, the diverter segments can all be movable on an inclined track to retract against a bias force for fluid bias with movement of the tool in the opposite direction allowing the bias to push the segments on the inclined track for diversion of debris laden fluid into a capture volume in the tool.

摘要： In one variation, a tool is disclosed that can run cladding into casing where the cladding interior is closed off by opposed cup seals and access to the volume between the cup seals exists through the tool body. “Cladding” comprises sleeves, scrolls, casing, tubing and liner strings. Pressure is applied to the interior of the cladding to expand it into gripping and sealed contact with the casing. An exterior gripping surface can be provided on the cladding to enhance grip upon expansion. The tool can be repositioned to expand lengths of cladding including tubing or casing.
