Abstract
A resilient sealing element is adapted for connection to a well tool, with an integral anchoring device, such as a slip, embedded therein. When compressive forces are applied thereto the sealing element compresses and moves its outside diameter and the slip into sealable engagement with the inside wall of a well tubing or casing. Releasing the sealing and anchoring element is accomplished by applying tension to a wire which passes longitudinally therethrough to cause retraction of the slip.
Claims11
An annular sealing and anchoring element for connection to a downhole tool, comprising:
- a cylindrical resilient sealing element;
- and
- at least one anchoring device embedded in an exterior longitudinal surface of said resilient sealing element, and adapted to be moved outwardly into engagement with a well tubular upon compression of the sealing element.
An annular sealing and anchoring element to be carried on a downhole tool, comprising:
- a cylindrical resilient sealing element adapted to be carried on a downhole tool;
- a plurality of anchoring devices embedded in and spaced radially about an exterior longitudinal surface of said resilient sealing element;
- first and second annular anti-extrusion rings spaced adjacent to respective first and second ends of said annular sealing element;
- and
- a plurality of tensile members, with each of said tensile members extending longitudinally through said sealing element, through a one of said anchoring devices, and through said first and second anti-extrusion rings.
