摘要
A method and apparatus for running in a tubing string through a high angle or horizontal wellbore without damage to equipment on the tubing string. Centralizers are mounted on the tubing string at spaced intervals on either side of the equipment. The centralizers include spherical rollers which contact the wellbore casing and which are mounted so as to have little or no radially inward movement.
