Composite well flow conductor

A well flow conductor, comprising:

• a composite liner tube composed of a plurality of overlapping, resin-bonded composite plies and adapted to conduct a fluid flow therethrough;
• a composite outer structure surrounding said composite liner tube and composed of a plurality of overlapping, resin-bonded composite plies arranged in a plurality of opposed helices about a centerline of said composite liner tube, said opposed helices intersecting at predetermined axial and radial locations on an outer surface of said composite liner tube to form nodes extending radially outwardly from said outer surface to form standoffs therefrom, said standoffs capable of centralizing said well flow conductor within an interior of a wellbore having a larger radius than that of said well flow conductor;
• an abrasion-resisting material located on said nodes to resist wearing of said nodes as said well flow conductor contacts said wellbore;
• and
• a sacrificial layer located on said composite outer structure and composed of a substantially fiber-free resin to isolate said nodes from direct contact with said wellbore as said well flow conductor contacts said wellbore.
