Abstract
A packer system includes a gauge ring, an expanding ring arranged adjacent to the gauge ring, a back-up ring, a packer element arranged adjacent to the back-up ring, and a support ring arranged between the back-up ring and the expanding ring. The support ring promotes radial outward expansion of the expanding ring.
Claims6
A packer system comprising:
- a tubular having a surface;
- a gauge ring provided on the tubular;
- an expanding ring arranged adjacent to the gauge ring, the expanding ring including a first angled surface abutting the gauge ring and a second, opposing angled surface having a first angled portion that extends at a first angle relative to the surface and a second angled portion that extends at a second angle relative to the surface, the first angle being non-perpendicular relative to the surface;
- a back-up ring including a first surface section and a second surface section, the first surface section extending at a non-perpendicular angle relative to the surface;
- a packer element arranged adjacent to the back-up ring, the first surface section and the second surface section encapsulating a portion of the packer element;
- and
- a support ring arranged axially between the back-up ring and the expanding ring, the support ring including a first angled surface portion that is complimentary to the first angle and a second angled surface portion that is complimentary to the first angled surface section, the support ring promoting radial outward expansion of the expanding ring.

A resource exploration and recovery system comprising:
- a surface system;
- and
- a downhole system including a string of tubulars, at least one of the string of tubulars including a surface supporting a packer system comprising:
- a gauge ring provided on the string of tubulars;
- an expanding ring arranged adjacent to the gauge ring, the expanding ring including a first angled surface abutting the gauge ring and a second, opposing angled surface having a first angled portion that extends at a first angle relative to the surface and a second angled portion that extends at a second angle relative to the surface, the first angle being non-perpendicular relative to the surface;
- a back-up ring including a first surface section and a second surface section, the first surface section extending at a non-perpendicular angle relative to the surface;
- a packer element arranged adjacent to the back-up ring, the first surface section and the second surface section encapsulating a portion of the packer element;
- and
- a support ring arranged axially between the back-up ring and the expanding ring, the support ring including a first angled surface portion that is complimentary to the first angle and a second angled surface portion that is complimentary to the first angled surface section, the support ring promoting radial outward expansion of the expanding ring.
