摘要： The present invention notably concerns a method for repairing a hanger (D) of a liner (B), with a view to making it leak-tight, this liner (B) being placed inside and in the continuation of the casing (A) of a well.It is characterized by the fact that, during a first phase, it consists of axially positioning a metal tubular blank (1) in the well, the blank having a solid wall radially deformable beyond its elastic limit and comprising an upper cylindrical portion (10) whose outer diameter is slightly smaller than the inner diameter of the casing (A), a lower portion (13) also cylindrical whose outer diameter is slightly smaller than the inner diameter of the liner (B), and an intermediate portion (11, 12) of diameter varying between these two diameters, this positioning being performed so that said lower portion (13) comes to be housed in the mouth of the liner (B) whilst said upper portion (10) comes to lie opposite the zone of the casing (A) located above the hanger (D), then—during a second phase—of causing the radial expansion of at least one of these two cylindrical portions (10, 13) beyond its elastic limit so that they are applied closely and firmly and in leak-tight manner against the inner face of the wall opposite the casing (A) or liner (B), and so that subsequent to this expansion the intermediate portion (11, 12) of the blank (1) covers the hanger.

摘要： The present invention relates in particular to a lining process for a line (C) using hydroforming of a liner (3), according to which: a) a tool (1) is inserted axially into said liner (3) whereon are mounted two radially expandable plugs (2); said tool (1) is positioned inside the liner (3) so that the plugs (2) are located facing its end portions (33); the plugs (2) are slightly expanded so as to bind the tool (1) to said liner (3); the assembly consisting of the tool (1) and the liner (3) is inserted axially into the well or the line (C); fluid under pressure is sent into the liner (3), between the two plugs (2) so as to cause radial expansion of only the central portion of the liner (3); eventually, said plugs (2) are again expanded with sufficient pressure for them to cause radial expansion of the two end portion (33) of the liner (3), applying them against the inner wall (Cp) of the line (C); said plugs (2) are retracted and the tool (1) is withdrawn from the line (C), characterized by the fact that retraction of said plugs (2) is carried out by generating a vacuum inside them.
