Annular barrier and annular barrier system and method |
摘要 |
The present invention relates to an annular barrier system (100) for expanding an annular barrier (1) in an annulus (2) between a well tubular structure (3) and an inside wall (4) of a borehole downhole. The annular barrier system comprises an annular barrier (1) having a tubular part (5) for mounting as part of the well tubular structure (3), the annular barrier further comprising an expandable sleeve (6) surrounding the tubular part (5), at least one end (7) of the expandable sleeve being fastened in a fastening means (8) of a connection part (9) in the tubular part. The annular barrier system also comprises a tool (20) for expanding the expandable sleeve by letting a pressurised fluid through a passage (11, 21) in the tubular part into a space (12) between the expandable sleeve and the tubular part. |
