<p>Described herein is a tubular apparatus for the continuous completion of wells for hydrocarbons, of the type comprising a flexible cylindrical wall (11; 11′) defining inside it a hollow passage (19) suitable for being wound, in particular on a spool, and laid for use in the step of completion of a drilling well. According to the invention, said cylindrical wall (11; 11′) comprises a fabric (12, 13, 15; 12′, 13′, 15′) including inside it at least one gap (14; 14′), which develops in the axial direction of said cylindrical wall (11), said fabric (12, 13, 15; 12′, 13′, 15′) comprising means suitable for operating under traction (15; 15′) when within said at least one gap (14; 14′) a pressurized fluid (20) is present injected for stiffening the tubular apparatus (10; 10′).</p> |
