Abstract

See full text

Apparatus for injecting tubing into a subterranean well comprising a support frame for a pair of opposed endless conveyor chains fitted with tubing gripper blocks for gripping and conveying the tubing into and out of the well. The conveyor chains are supported by movable ramp members which are each connected to opposed hydraulic cylinder actuators hydraulically interconnected in parallel so that the ramp members may be moved toward and away from each other to uniformly vary the gripping force of the conveyor chains on the tubing. The endless conveyor chains are trained over idler sprockets which are interconnected by opposed hydraulic cylinder actuators for tensioning the chains with substantially equal tensioning forces. The conveyor assembly is mounted on a frame comprising two spaced apart metal plates which are reinforced by spaced apart vertical column members supported on a base. A guide mechanism for the tubing approaching the apparatus from a supply reel is provided with a series of spaced apart guide roller assemblies which are adapted to guide the tubing in both horizontal and vertical planes. The guide mechanism includes a support boom which is connected to the frame for swivelling movement to align the support boom with the injection tubing as it is paid out or back onto a supply reel. The conveyor chains are driven by sprockets connected to hydraulic motors connected in parallel.
