ABSTRACT:
A coiled tubing injector assembly includes a coiled tubing injector and a tubing guide. The tubing guide has an automatic clamping mechanism that includes a pair of clamping slips. The clamping slip will automatically move from an open position in which coiled tubing can pass through the clamping sips, to a closed position in which the clamping slips positively clamp the coiled tubing to the tubing guide. The clamping mechanism moves from the open to the closed position when the tubing guide is lifted from an installation platform in which the coiled tubing is positioned in the tubing guide so that it can be positioned on top of the coiled tubing injector. The clamping mechanism will automatically clamp the coiled tubing to the tubing guide when the tubing guide is removed from the coiled tubing injector.
