    摘要: Tools for expanding downhole tubulars into each other or in open hole are disclosed. One embodiment uses a movable cone biased by Bellville washers to move longitudinally against such bias and allow collets to move radially in or out to a predetermined maximum diameter. A release system allows collet retraction to avoid hang up on removal. In an alternate embodiment, more suitable for open hole applications, pressurized gas pushes a movable cone longitudinally against the collets. A stationary cone is on the opposite side of the collets from the movable cone. The collet rides out or in between the cones and raises the gas pressure when forced in. A pressure actuated release allows the lower cone to shift downwardly to allow the collets to retract for removal.

    摘要: A swaging tool is configured to drive the swage up a ramp until a series of dogs engages the inside wall of an outer tubular member. At that point the swage will be at the necessary position on the ramp to adequately expand the inner tubular for a proper supporting relation to the outer tubular. If the inside diameter of the outer tubular is at the high end of the tolerance allowed by API specifications, the diameter of the swage is increased to compensate. Similarly, if the inside diameter of the outer tubular is at the low end of the tolerance range of API specifications, then the dogs make contact with the inside wall sooner and the resulting diameter of the swage is necessarily smaller.

    摘要: A tool allows in a single trip advancing the liner while more hole is made until the liner is properly positioned. Slips are actuated into the inside of the liner to grasp it as a swage is released to move to support the liner to the surrounding tubular. With the liner supported in the hole, the running tool can be picked up to test the release feature and then set down again for cementing. The tool is then picked up higher to release a flapper and re-pressurized to set a seal adjacent the support previously engaged by swage operation. The flapper has a rupture disc blown and the tool is removed. The tool has an emergency release.

    摘要: A wiper plug for downhole use is disclosed. It features an inflatable structure that allows it to ride inside tubulars that change or gradually vary in inside diameter. In a preferred embodiment the bladder is actuated by fluid displaced by a biased piston. The piston is capable of moving in opposite directions to allow original insertion into a launcher and subsequent bladder expansion. In another embodiment, the piston can be fluid driven in opposed directions by a pump and an on board control system which can regulate, on a real time basis, the contact pressure of the bladder to a predetermined level or range, as the bladder encounters varying interior wall diameters of the tubular string or associated equipment.

    摘要: A composite landing collar is disclosed which is preferably adhesive bonded to the liner string using a high temperature epoxy. The spacing during bonding is maintained within dimensional limits using spacers. The body features a bi-directional material, with an appropriate ratio in the warp and fills directions, for about a quarter of the wall thickness. A unidirectional material with the fibers axially aligned aids in reduction of thermal stresses in the thick wall during curing, as well as reducing shear stress concentration along the adhesive bonding interface.

    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: A plug-dropping head capable of dropping balls or plugs or other objects is disclosed. The plug-dropping head has a compact design with a cylinder having multiple chambers for storage of plugs and/or balls. The device can be actuated manually or automatically, locally or remotely, to rotate the cylinder to present a different bore in alignment with a flowpath through the housing. An exterior signal indicates that the object has fallen through the device. An indexing feature assures alignment of the individual bores in the cylinder which contain a plug or wiper with the main passage through the tool. Flow can be maintained through the tool as the cylinder is rotated. Rotation of the cylinder allows an obstruction device in the flowpath to move out of the way to allow the ball or plug to drop when sufficient alignment is reached.

    摘要: A combination landing unit and seal assembly is shown for engaging and sealing within the internal bore of the liner within a well. A special latch mechanism carried on the seal assembly includes an externally threaded latch collet which can be stabbed into the setting sleeve threads which are normally provided in the interior of the liner for use with the running tool which installs the liner in the well bore. An integral seal assembly is carried in the assembly in an upward extension of the landing unit and floats within a tubular extension of the landing unit. A plug can be installed in the landing unit to allow the seal assembly to be retrieved to the well surface without killing the well.

    摘要: A wiper plug release tool uses a first pump down plug that lands in the tool to pressurize an internal chamber to slide a sleeve that undermines a set of dogs to allow the lower wiper plug to be decoupled from support. The shifting of this sleeve cams a second set of dogs into an internal passage in the tool to act as a landing location for a second pump down plug. Landing the second pump down plug on the now extended dogs allows a net pressure to be applied to an upper piston which shifts a sleeve to release the support for the second wiper plug. The upper piston remains in pressure balance unless the second pump down plug can be landed on the dogs that only extended because the sleeve that released the lower wiper plug had shifted.
