Abstract: A coiled tubing injector apparatus for use in inserting coiled tubing into a well, temporarily suspending the coiled tubing, and removing the coiled tubing from the well is described. The apparatus includes a base with a pair of spaced-apart carriages extending upwardly therefrom. The base is part of a frame positioned above a wellhead. The carriages each have a gripper chain drive system rotatably mounted thereon and movable therewith. An actuation and linkage system allows the carriages to move toward and away from one another in a lateral or transverse direction with respect to the superstructure and the base. Thus, the gripper chain systems comprises gripper chains that can be engaged or disengaged from the coiled tubing extending through the apparatus. A wetting fluid basin is positioned below the gripper chains, and support guides engage the coiled tubing below the gripper chains to prevent buckling of the coiled tubing. The gripper chain drive system includes idler sprockets mounted on an idler sprocket shaft. The position of first and second ends of the idler sprocket shaft are monitored, and may be adjusted to maintain a parallel relationship with a drive sprocket shaft on which are mounted drive sprockets supporting the gripper chain.

Abstract: A gripper block for use in grippingly engaging coiled tubing, pipe, rod, cable or like objects having various outside dimensions is provided. The gripper block has a gripping portion which includes a curved and a planar gripping surface. The planar gripping surface preferably includes a pair of opposed sloped planar gripping surfaces to engage coiled tubing, preferably steel coiled tubing of varying diameters. The sloped gripping surfaces preferably provide a V-shaped engagement configuration. The curved gripping surface is adapted to engage coiled tubing, preferably composite coiled tubing having a diameter less than the coiled tubing to be engaged by the sloped gripping surfaces.
