Abstract (en)
[origin: US5964288A] PCT No. PCT/FR96/01225 Sec. 371 Date Jul. 20, 1998 Sec. 102(e) Date Jul. 20, 1998 PCT Filed Aug. 2, 1996 PCT Pub. No. WO97/06345 PCT Pub. Date Feb. 20, 1997The device includes a radially deformable flexible tubular preform (1) that can be expanded by internal pressure and hardened in situ by heating its wall to polymerize it, the preform is formed of a rectilinear main section (10 and a rectilinear secondary section (11) at an acute angle ( alpha ) to the main section (10) and joined and sealed to the latter in a middle area (10c), temporary restraining bindings being provided to hold the secondary section initially in a radially folded condition, pressed against the main section (10), the combination then constituting a rectilinear preform, whereas after removal of the temporary restraining bindings (3), and due to internal pressure, the secondary section (11) separates from the main section (10), the combination then constituting a generally "y" shape preform adapted to be polymerized in the area of bifurcation of the well.
