Definitions

  • This invention relates generally to hydrocarbon exploration and production, and more specifically to the field of casing patches for wellbore casings.
  • a casing patch system for installing a casing patch in a wellbore formed in an earth formation, the casing patch system comprising a base tubular comprising an internal diameter, and a first anchor/seal and a second anchor/seal coupled to the base tubular, wherein internal diameters of the first and the second anchor/seals are less than the internal diameter of the base tubular.
  • the casing patch system may comprise an expansion tool comprising a first expansion device and a second expansion device coupled to a shaft; a second expansion device positioned inside the base tubular between the first and second anchor/seals, and a distance between the first and second expansion devices selected such that upon expansion of the first anchor/seal by the first expansion device the second expansion device approximately engages the second anchor/seal; and a thruster coupled to a releasable support and the shaft, and the thruster is capable of providing a force necessary for expansion of the anchor/seals.
  • a casing patch is thereby achieved by positioning expansion devices as described above to minimize the expansion force due to sequential expansion and the length of the displacement necessary for setting the casing patch without resetting the thruster, instead of stroking the thruster multiple times as in previous efforts, which allows deployment and setting of the casing patch on a wireline.
  • the expansion device may comprise a dual swage system comprising a front swage and a back swage coupled to a shaft at a distance between them approximately equal to the length of the anchor/seal.
  • the front swage has a diameter less than the diameter of the back swage.
  • the swage diameters may be selected such that the expansion forces of the anchor/seal by the front and back swages may be approximately equal, resulting in significantly less expansion forces compared to the expansion force necessary for expanding an anchor/seal by a single swage. This may prevent localized buckling of the anchor/seals or base tubular in cases of high expansion ratios for setting anchor/seals to the well casing.

  • the thruster 18 is pressurized pulling the first and second expansion devices 14 and 15 towards the thruster 18.

Abstract

Cette invention concerne un système de pièce de réparation pour tubage comprenant un élément tubulaire de base doté de deux éléments d'ancrage/joints accouplés à l'élément tubulaire de base et un outil expanseur comprenant un dispositif expanseur comprenant deux matrices couplées à un arbre se trouvant entre elles à une distance approximativement égale à la longueur de l'élément d'ancrage/joint. Les diamètres des matrices sont sélectionnés de telle sorte que les forces d'expansion exercées sur l'élément d'ancrage/joint par les matrices avant et arrière sont approximativement égales, ce qui permet d'obtenir une force d'expansion significativement inférieure à la force d'expansion nécessaire à l'expansion par une seule matrice, ce qui permet d'obtenir un degré élevé d'expansion de l'élément d'ancrage/joint qui ne peut être atteint avec des dispositifs expanseurs à matrice unique.
