    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.

    摘要： A pumping system including a fluid inlet line and a primary pump for the fluid. The primary pump includes an impeller in an impeller chamber, with the impeller chamber adapted to receive fluid from the inlet line. A suction chamber is above the impeller chamber, with a throttle opening between the impeller chamber and the suction chamber. A priming pump is adapted to draw fluid through the throttle opening into the suction chamber. A fluid path is provided around the impeller chamber and between the inlet line and the suction chamber, with the fluid path having a larger area than the throttle opening and including a float restrictor.
