A composite tubular member having an outer cylindrical member containing fibers oriented to resist internal pressure while providing low bending stiffness, an inner smaller centrally located core member located near the neutral axis of the composite tubular member and containing fibers oriented to provide high axial stiffness, high tensile strength and low bending stiffness. One or more web members contain fibers oriented to resist shear stress, and connect the outer cylindrical member and the inner core member to form at least two separate cells within the composite tubular member. The web member forms a major and minor moment of inertia within the tubular member to create a preferred bending direction. Conductors are formed integral to the connecting web member for transmitting energy signals through the tubular member.
A composite tubular member for use in well operations wherein the tubular member is in use stored on a spool at the surface of a well and is unspooled and spooled as it is lowered and raised respectively into and from the well, comprising;
A composite spoolable tubular member having a central longitudinal axis and comprising an outer composite cylindrical member containing fibers cross-piled and angularly oriented to the central longitudinal axis of the tubular member, a smaller inner centrally located composite member extending along the central longitudinal axis of the tubular member and having fibers oriented at 0.degree. to the central longitudinal axis of the tubular member;
A composite tubular member for use in well operations wherein the tubular member is in use stored on a spool at the surface of a well and is unspooled and spooled as it is lowered and raised respectively into and from the well, comprising;
