Anisotropic composite tubular emplacement

The method of claim i wherein the anisotropically tailored tubular comprises an aramid, carbon, glass, or metal filament or fiber or band as a reinforcing component and comprises a matrix of a high strength organic thermosetting or thermoplastic resin.

An anisotropically tailored tubular suitable for running into a depth extended aperture by impressing at least one of compression stress along the long axis of the tubular, or tension stress along the long axis of the tubular, or pressure on the interior of the tubular, during the course of the running such that localized twisting and/or extension and/or bending is imparted to the tubular along its length during the course of the running, thus decreasing frictional resistance to the running, the anisotropic tubular fabricated of a composite having an unsymmetrical bias of the reinforcing components of the composite and an elasticity of the matrix thereof such that at least one of (a) compression stress along the long axis of the tubular or (b) tension stress along the long axis of the tubular or (c) pressure on the interior of the tubular will cause localized twisting and/or extension and/or bending of the tubular along its long axis.

A composite coiled tubing system for use in a wellbore to perform wellbore operations, comprising;

• a strong tubular structure having sufficient elasticity for spooling said tubing about a reel at the surface of the wellbore;
• reinforcing components arranged about said tubular structure and including fibers bound together in a matrix to form individual lamina;
• said lamina being arranged about said tubular structure to form a composite tubing that has an unsymmetrical bias of the reinforcing components such that the tubular structure exhibits anisotropic properties when subjected to changes in thermal mechanical or hydraulic effects applied to said composite tubing to cause rotary or axial motion of said composite tubing.
