    • 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.
    • 各向异性定制的管(由具有复合材料的增强部件的不对称偏压的复合材料制成,并且其基体的弹性使得沿着管的长轴的压缩应力或沿着长轴的拉伸应力的至少一个 管状内部的管状或压力将引起管状物沿着其长轴线的局部扭曲和/或延伸和/或弯曲)进入深度延伸孔,同时使局部扭转和/或延伸和/或弯曲至 通过施加沿着管状物的长轴的压缩应力或沿着管状物的长轴的拉伸应力或管状内部上的压力中的至少一个压缩应力,沿着其长度在其运行过程中的管状物。 因此,通过局部扭转,弯曲和/或延伸减小了对运行的摩擦阻力。 因此,通过克服由静态摩擦力卡住的趋势 - “摆动蜗杆”效应,可以获得长距离穿越的能力。
