ANNULAR BARRIER AND ANNULAR BARRIER SYSTEM

摘要

The present invention relates to an annular barrier system for expanding an annular barrier in an annulus between a well tubular structure and an inside wall of a borehole downhole. The annular barrier system comprises an annular barrier having a tubular part for mounting as part of the well tubular structure, the annular barrier further comprising an expandable sleeve surrounding the tubular part, at least one end of the expandable sleeve being fastened in a fastening means of a connection part in the tubular part. The annular barrier system also comprises a tool for expanding the expandable sleeve by letting a pressurised fluid through a passage in the tubular part into a space between the expandable sleeve and the tubular part.
