Title
(EN) CENTRALIZING AND PROTECTING SABOT
(FR) SABOT DE CENTRALISATION ET DE PROTECTION
Abstract
(EN)
A system for setting a seal (200, 300, 400) in a wellbore includes a sabot (230, 330, 412) being supported by the seal (200, 300, 400) and having a first diameter (232, 332, 414) larger than a second diameter (222, 322, 420) of the seal (200, 300, 400). The system also includes a bridge (240, 340, 424) coupled to the sabot (230, 330, 412), the bridge (240, 340, 424) extending axially away from the sabot (230, 330, 412) and positioned within a slot (228, 328) formed by an extension (212, 312, 418). The system also includes an energizing ring (308, 402) that applies a radial force to a leg (206, 306, 404) proximate the sabot (230, 330, 412) to at least partially deform the sabot (230, 330, 412).
(FR)
La présente invention concerne un système pour positionner un joint d'étanchéité (200, 300, 400) dans un puits de forage, ledit système comprenant un sabot (230, 330, 412) qui est supporté par le joint d'étanchéité (200, 300, 400) et qui a un premier diamètre (232, 332, 414) supérieur à un second diamètre (222, 322, 420) du joint d'étanchéité (200, 300, 400). Le système comprend également un pont (240, 340, 424) couplé au sabot (230, 330, 412), le pont (240, 340, 424) s'étendant axialement pour s'éloigner du sabot (230, 330, 412) et étant positionné à l'intérieur d'une fente (228 328) formée par une extension (212, 312, 418). Le système comprend également un anneau de sollicitation (308, 402) qui applique une force radiale sur un segment (206, 306, 404) à proximité du sabot (230, 330, 412) pour déformer au moins partiellement le sabot (230, 330, 412).
