Definitions

  • the present disclosure relates in general to apparatus and methods for connecting sections of pipe, and in particular but not limited to pipe sections connected to form casing strings for oil and gas wells.
  • the disclosure relates to a coupling for connecting the ends of pipe sections.
  • connection failure occurs when the coupling is essentially axially rigid with respect to the casing pipe, and where the connection is subjected to simultaneous axial tension and bending of high magnitude.
  • the typical failure of this example of connection results in localized yielding of the casing at the start of the thread that is cut into the outside of the casing to form the pin thread. This localized yielding is created by very high stresses in a small area, and if significant strain is added to this stress, ultimate casing failure will result.
  • the corrugated section being adapted to accommodate transverse deflection while maintaining torsional, compression/tension and pressure performance characteristics of the base pipe segments.
  • the coupling of the invention includes a corrugated section for accommodating bending/transverse stresses normally subjected on the threaded section of the pin and box connection.
  • the coupling of the invention is designed so that bending/transverse loading does not adversely affect the thread engagement between the pin thread and the box thread.
  • the coupling of the invention wherein the section thickness and radius of the corrugated section can be tuned to accommodate optimum bending/transverse stiffness, thereby minimizing stress on the adjacent pipes and their relative threads.
  • FIG. 1 schematically illustrates a coupling according to one aspect of the invention. As illustrated, the coupling 2, includes a central bore extending between coupling ends.
  • pin seal rings will be referred to herein in the singular as they function as a single element having two opposed faces.
  • the presence of the pin seal ring 8 on the coupling is preferred but not mandatory.
  • the pin seal ring 8 is formed as part of the inner surface of the coupling.
  • the pin seal ring may be a separate element provided or placed within the bore of the coupling. The pin seal ring 8 is also helpful in directing any deflection stresses towards the central body portion of the coupling 2 and away from the threaded connections between the coupling and the tubular members 1.
  • centralizer ring 9 serves to mitigate against the transmission of lateral stresses or loads encountered by the casing string from being absorbed by the threads 3 and transferring those loads into the corrugated section 20 of the coupling 2 and then onto the body of the attached tubular member 1 .
  • centralizer ring 9 and pin seal ring 8 will react against the outer surface and pin face of tubular member 1 and thus prevent any deformation of the pin end within coupling 2 that would otherwise induce thread separation of pin and box threads 3 within coupling 2.
  • Coupling 2 is compatible with or can be adapted to use any known thread design used to connect oilfield tubulars. Many existing coupling designs are configured to provide for nose-to-nose sealing of the pin ends of the tubular members being connected when they are screwed into the coupling. Analogous seals will be effected using couplings in accordance with the present disclosure, but instead of the two pin noses sealing against each other, they will seal against pin seal ring 8.
  • any use of any form of the terms “connect”, “engage”, “couple”, “attach”, or any other term describing an interaction between elements is not meant to limit the interaction to direct interaction between the subject elements, and may also include indirect interaction between the elements such as through secondary or intermediary structure. Relational terms such as "parallel”,
