ABSTRACT:
A tubing injector apparatus for guiding coiled tubing and inserting the tubing into a well. The apparatus includes a tubing guide portion which has a curvilinear first frame and a curvilinear second frame spaced from the first frame. An elongated first guide track is attached to the first frame, and a second guide track is attached to the second frame. The guide tracks are adapted for sliding engagement by the tubing as the tubing is moved through the injector apparatus. The guide strips are preferably made of a self-lubricating material so that the tubing moves easily.
