Method and apparatus for injection of tubing into wells
A tubing injector is described comprising: a frame; a subframe slidably mounted on the frame; tubing storage means mounted on the subframe and having coil tubing stored thereon; an injector reel rotatably mounted on the frame; means for rotating the injector reel; means mounted around a portion of the circumference of the injector reel for exerting pressure against the coiled tubing when the coil tubing is directed between the pressure exerting means and the circumference of the injector reel to provide positive engagement of the tubing by the injector reel when the injector reel is being rotated to pull the tubing off of the tubing storage means or return the tubing to the tubing storage means; means for straightening the tubing; and means for slidably reciprocating the subframe across the frame during the return of the tubing to the tubing storage means.
