DEVICE FOR DELIVERING CORROSION OR DEPOSITION INHIBITING AGENTS INTO A WELL BY MEANS OF AN AUXILIARY DELIVERY TUBE

摘要

A new auxiliary injection tube concept is disclosed for injecting a fluid containing corrosion and/or deposit inhibiting agents into a well from the surface, without stopping working. The invention comprises a tube 10 conveying the injected agents, coated with a material 11 which is inert with respect to to the fluid collected by the well and support cables 12, disposed about the tube 10 and also coated with material 11 providing both secondary protection of the tube 10 in the case of damage to coating 11 and the mechanical characteristics required for the injection tubs, particularly during withdrawal from the well.
