METHOD OF FINISHING WELLS

WIPO Patent Application WO/1995/003476

A1

The method disclosed of finishing a well involves lowering and hermetically joining a casing column (2) the well (11) with shaft section (3) and filter (4). Before lowering the pieces into the well (11), at least one of the pipes (12) of the shaft section (3) with filter (4) is shaped in such a way as to create at least two longitudinal corrugations (13) and cylindrical ends (25) with threads (26). The productive layer (18) is then opened up, and once the shaft section (3) has been lowered into the said layer, the shaped pipe (12) is expanded to secure the shaft section (3) in the well (11) and to separate non-productive and productive layers.
