摘要： The present invention relates to a method and apparatus for anchoring an expandable tubular within a wellbore prior to expanding the length of the expandable tubular into contact with the wellbore. An expandable system comprises the expandable tubular and a deployment tool, wherein the deployment tool exerts radial force against the expandable tubular to expand at least a portion of the expandable tubular into contact with the wellbore to anchor the expandable tubular prior to the expansion process. A method for anchoring an expandable tubular within a wellbore prior to the expansion process is also provided, wherein radial force expands the expandable tubular into contact with the wellbore to initially anchor the expandable tubular. A method for altering the shape of the anchor is also provided.

摘要： The present invention generally relates to an apparatus for sealing a wellbore. The sealing apparatus includes an expandable tubular body having one or more sealing elements disposed thereon. In one aspect, the sealing elements include swelling and non-swelling sealing elements. Preferably, the swelling sealing elements are made of a swelling elastomer capable of swelling upon activation by an activating agent. The swelling elements may be covered with a protective layer during the run-in. When the tubular body is expanded, the protective layer breaks, thereby exposing the swelling elements to the activating agent. In turn, the swelling elements swell and contact the wellbore to form a fluid tight seal.

摘要翻译：本发明一般涉及用于密封井筒的装置。密封装置包括一个具有一个或多个密封元件的膨胀管状体。在一个方面，密封元件包括溶胀和非膨胀的密封元件。优选地，膨胀密封元件由能够在活化剂活化时膨胀的膨胀弹性体制成。膨胀元件在入料期间可能被保护层覆盖。当管状体膨胀时，保护层破裂，从而将溶胀元件暴露于活化剂。反过来，膨胀元件膨胀并接触井筒，形成流体密封。
