Metal Back-Up Ring For Downhole Seals
US Patent:

Filed:

Appl. No.:
8/828768

Abstract:
A sealing element for a packer or bridge plug or other downhole tool is illustrated which employs the use of back-up rings above and/or below a resilient seal. The various sleeves which are moved with respect to each other to compress the sealing element are made so that they are physically connected to the back-up rings. As a result, upon run-in, inadvertent compression of the seal is prevented and upon release, a physical separation occurs between the back-up ring and the sealing element, which allows the sealing element to expand and relax. Subsequent upward movement of the packer or bridge plug easily deflects the back-up ring since the sealing element is no longer in a compressed state directly underneath it. The packer then can easily be removed.
