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 carriages extending upwardly therefrom. The base is attached to a superstructure. 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 can be engaged or disengaged from tubing extending through the apparatus. Each of the carriages are pivotally attached to the base with a load pin which extends through lugs attached to the base and corresponding lugs extending down from the carriage.

Coiled tubing injector apparatus

An apparatus for guiding and directing tubing into a coiled tubing injector apparatus is disclosed. The tubing guide will direct the tubing into the coiled tubing injector apparatus for insertion or removal into the wellbore therebelow. The natural, or residual radius of the tubing is utilized to direct the tubing into the coiled tubing injector apparatus, so that minimal bending is applied to the tubing.

Tubing guide with optimized profile and offset

A method and apparatus for running wireline and reeled tubing into a wellbore in which an adapter tube extends through the reeled tubing injector to enable the wireline rig to be mounted on the reeled tubing rig. A stuffing box is also provided which can easily be converted to accommodate wireline or to accommodate reeled tubing.

A connecting apparatus for two tubular members including an adapter sleeve extending over the end portion of one of the members in a coaxial relationship therewith and adapted to abutt the end of the other member. A threaded nut means extends over the adapter sleeve in engagement therewith, and is adapted to threadedly engage the outer surface of the corresponding end portion of the other member to connect the members together. The adapter sleeve increases in cross-section in a direction towards the end of the one member to decrease the stress on the latter member accordingly.
