ABSTRACT:
In the use of composite materials for a coiled tubing for downhole use, precise external tubular dimension and durable wear surface become a critical factor because of the potential for damage to the external surface as the tubing passes through the stripper assembly at the wellhead which is provided to control high pressures within the well. An infuser arranged within the stripper provides lubrication for the passage of the composite tubing through the sealing members within the stripper and also infuses fluids into microfissures and cracks naturally occurring on the surface of the composite tubing to fill the voids and thereby enhance the structural integrity of the tubing.
