    摘要： A method for providing a string of tubing for installation in a well, which method comprises installing a string of tubing within a wellbore. The string of tubing comprises a plurality of elongated tubular members and at least one cylindrical liner comprising a polymer. At least one of the plurality of elongated tubular members includes a cylindrical wall having an inner surface and an outer surface. The cylindrical liner has an outer surface that is disposed in adjacent contact with the inner surface of the elongated tubular member. The cylindrical liner has an inner surface that defines the tubing borehole through which fluids are capable of flowing. The cylindrical liner has a scrolled configuration.

    摘要： The installation and use of abrasion and corrosion resistant polyolefin and polyolefin blend liners in the production or injection string of a well is shown. The lining is employed for the principal purpose of reducing wear or corrosion on the tubing string or wear on the associated production equipment. In a preferred embodiment of the invention, the polymer liner is characterized by polypropylene material, which is abrasion resistant and which has a coefficient of friction that is lower that the coefficient of friction of metal tubing. Also, disclosed herein are tubular goods and tubular good liners which decrease or eliminate friction and mechanical wear and decrease or eliminate chemical corrosion to the walls of the tubular good. The liners may include a diffusion barrier, an adhesive, and a friction and wear resistant layer.
