Isolation Barrier

摘要

An apparatus and method for securing a tubular within another tubular or borehole, creating a seal across an annulus in a well bore, and centralising or anchoring tubing within a wellbore. A sleeve is arranged on a tubular body to create a chamber therebetween. A port provides fluid access through the body to the chamber. A torsion spring is located within the chamber. When fluid is introduced into the chamber the sleeve is morphed to secure it to a well bore wall and the torsion spring unwinds to a relaxed state. The relaxed torsion spring supports the morphed sleeve against collapse.

主权项

1. An assembly, comprising:
a tubular body arranged to be run in and secured within a larger diameter generally cylindrical structure; a sleeve member positioned on the exterior of the tubular body, to create a chamber therebetween; the tubular body including a port to permit the flow of fluid into the chamber to cause the sleeve member to move outwardly and morph against an inner surface of the larger diameter structure; and characterised in that: at least one torsion spring is located within the chamber; the torsion spring relaxing as the sleeve member is moved outwardly by fluid pressure to provide a frame within the chamber when the sleeve member is morphed against the inner surface of the larger diameter structure.
