摘要： A crimping tool is disclosed that includes a housing assembly carrying a crimping assembly having jaws with engagement surfaces designed to move in the radial direction under controlled load and controlled displacement with application of hydraulic pressure to pistons provided to load the jaws. The crimping tool is designed to be separable into two parts, which facilitates assembly and disassembly of the tool around the work piece for crimping at locations remote from the end of a continuous or long section of pipe. This tool is adapted for use in crimping end fittings onto composite pipe and for use in a field environment where the tool is manually transportable.

摘要： A seal cup and method is disclosed that can be used on a wellbore tool. The seal cup includes an external circumferential seal land adjacent the cup lip and an outer surface capable of permitting drainage away from the seal land of fluids, which may seep past the seal land. This acts against pressure invasion in the interfacial contacting region between the seal cup and the structure, for example, a wellbore liner against which it is sealed.

摘要： A slotting geometry for a metal pipe for use in fabricating slotted liners. The slotting geometry includes one or more integral substantially continuous unslotted helical coils extending around a peripheral sidewall for sustantially the entire length of a tubular body. There are helical regions between the coils containing slots arranged to create generally trapezoidally shaped elongated struts joining the edges of adjacent coils. Ends of the tubular body have unslotted connecting portions, thereby facilitating connection with the tubular body. Slotted liners fabricated using this slotting geometry have the capability of having their outer diameter expanded or contracted. This has utility when inserting or removing the slotted liners iinto a well bore. By expanding or contracting the outer diameter, the slots can be made to be sider or narrower, this has utility in controlling slot width.

摘要： A plurality of steel rings are crimped or shrink fitted onto a joint of steel well casing to produce the casing anchor. The rings and joint are sufficiently interlocked so that, when the anchor is cemented in a well, the joint can transfer axial load from the casing string to the cement through the rings to provide resistance to axial displacement of the anchor relative to the surrounding earth material.

摘要： A cementing adaptor includes a cylindrical carrier carrying a casing seal, a middle interval and a lower end separated by an annular rib, and a cylindrical swivel element disposed around and coaxially rotatable relative to the middle interval. A cylindrical connector has an upper end rotatably disposed around the carrier's lower end and non-rotatably connected to the swivel element, plus a lower end connectable to an inner tubular string. With the carrier's upper end connected to a casing running tool (CRT), this assembly can be disposed within a casing string with the casing seal engaging the casing and preventing fluid flow into the casing annulus below the seal when cement is pumped down the inner string, such that the cement is urged into the wellbore annulus. The swivel connection limits torque transfer that might otherwise overload the CRT or its connection to the cementing adaptor.

摘要： A shoulder ring, for installation in a threaded pipe coupling between the installed pin ends of two pipes being connected by the coupling, has opposing end faces and a central opening, and may be lobate or circular in shape. The shoulder ring provides enhanced axial retention within the coupling by incorporating a thread element which engages the internal threads of the coupling to prevent or deter displacement of the ring from the coupling. Alternatively, enhanced axial retention may be provided by means of an interference or interlocking fit that is plastically induced during the ring installation process. The shoulder ring may be of lobate or circular configuration, with the axial retention of lobate embodiments being further enhanced by forces acting radially outward against the coupling due to elastic deformation of the ring during installation. Also disclosed are tools for installing the shoulder rings in a threaded coupling.

摘要： A gripping tool includes a body assembly and gripping assembly with a grip surface adapted to move from a retracted position to an engaged position to radially engage a work piece in response to relative axial displacement. A linkage is provided to act between the body assembly and the gripping assembly which, upon relative rotation in at least one direction, of the body relative to the grip surface results in relative axial displacement of the grip surface to activate the gripping elements. This tool was developed for use on drilling and service rigs having top drives, and supports rapid engagement and release, hoisting, pushing, and rotating.
