  • Tubing injector
    Patent number: 7073602
    Abstract: Apparatus for injecting coiled tubing into a bore comprises a rotatable housing (28, 29) having an axis along which coiled tubing is to be translated. A set of rolling elements (12, 14) is rotatably mounted in the housing (28, 29), each rolling element (24) having a skewed axis of rotation with respect to the housing axis and being arranged for rolling contact with an outside diameter of the coiled tubing. The arrangement is such that rotation of the housing (28, 29) relative to the tubing causes the tubing to be moved axially through the rotating housing.
