摘要

DEVICE USING COMPLEMENT A WELL CASING SUPPORT (2) STEEL ASSOCIATED column production or injection (3) COMPOSITES WITH a free ring (6). The invention relates to a device for protection of wells against the risks of corrosion or DEPOSITION DUE TO THE NATURE OF PRODUCE OR LOCATED IN FLUID WELL. CASING FORMED FROM A SUPPORT (2) STEEL associated with a production column (3) OF COMPOSITE MATERIALS WITH A RING (6) FREE ALLOWING PARTICULAR INJECTION WITHOUT STOPPING THE EXPLOITATION OF INHIBITORS. Column (3) is placed on the casing (2) by a device (4) which can be downloaded WHILE column (3) and having openings (13) ensuring the continuity HYDRAULIC RING (6). The device according to the invention is particularly adapted to wells CARRYING FLUIDS AGGRESSIVE NATURE WITH RESPECT TO TRADITIONAL STEEL intubated.
