摘要:
The present invention generally relates to an anchoring and sealing tool. In one aspect, downhole tool for use in a wellbore is provided. The tool includes a tubular having a tapered outer surface. The tool further includes an expandable annular member disposed on the tubular. The expandable member has an anchor portion. The tool further includes a seal member disposed in a groove of the expandable annular member. The seal member has one or more anti-extrusion bands, wherein the seal member and the anchor portion are configured to be expandable radially outward into contact with the wellbore as the expandable annular member moves along the tapered outer surface of the tubular.
