摘要:
A spoolable composite tube capable of being spooled onto a reel for storage and for use in oil field applications. The spoolable tube exhibits unique anistropic characteristics that provide improved burst and collapse pressures, increased tensile strength, compression strength, and load carrying capacity, while still remaining sufficiently bendable to be spooled onto a reel in an open bore configuration. The spoolable composite tube can include an inner liner, an interface layer, fiber composite layers, a pressure barrier layer, and an outer protective layer. The fiber composite layers can have a unique triaxial braid structure.

This invention relates to an improved termination connection for advanced fiber composite cables of the type comprised of fibers fixed in a matrix binder. In particular, the composite cable is provided with one or more ribs of tension wound binder impregnated fiber cured on the end portion thereof. Potting material is secured over the ribs at the end of the cable preferably having a parabolically curved outwardly tapered contour to distribute the longitudinal and transverse forces over the fibers in the cable.

An anisotropically tailored 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 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 will cause localized twisting and/or extension and/or bending of the tubular along its long axis) is run into a depth extended aperture while imparting localized twisting and/or extension and/or bending to the tubular along its length during the course of the running 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. Frictional resistance to the running is thus decreased by the localized twisting, bending, and/or extension. Ability to traverse long distances is thus obtained by overcoming the tendency to become stuck by static frictional forces--a "wiggle worm" effect.

Composite laminated tubing with low coefficient of thermal expansion and preferably a Poisson's ratio near 0.5 is used for production tubing which is subject to substantial expansion and contraction.

The drilling of highly angulated wellbores (with a rotary rig having a drill string terminated with a bit wherein drilling fluid is employed) is improved by employing in the highly angulated drill string a length of drill pipe which has a helical ridge disposed thereabout such that the flight of the helical ridge is wound so as to rise from the bit with the rotation of the drill string and the height of the helical ridge above the length of the surface of the drill pipe is 1 to 15 percent of the diameter of the drill pipe.

Well tools are run into a well, usually a deviated well, using a composite wireline cable made up of a bundle of parallel slideable composite rods covered with a flexible protective sheath.
