System for lining a wellbore |
摘要 |
The invention provides a system for lining a wellbore. The system comprises an expandable tubular element arranged in the wellbore, the tubular element having a first end part and a second end part whereby the second end part extends into a tubular wall located in the wellbore. An expander is arranged to radially expand the tubular element by movement of the expander through the tubular element in a direction from the first end part to the second end part, said direction defining an expansion direction. The system further comprises an anchor arranged to anchor said second end part to the tubular wall in a manner that the anchor substantially prevents movement of said second end part in the expansion direction and allows movement of said second end part in the direction opposite to the expansion direction. |
