Reel spool and stand assembly for coiled tubing injector system

摘要

A spool for carrying continuous pipe or coiled tubing for a coiled tubing injector is dropped into a stand at a site and coupled to a rotary power source. The stand includes two axles, on either side of the spool, and a drive coupling. A pipe slideably extends through one of the axles. It is retracted when the spool is lowered onto the stand and then extended for communicating fluid between the coiled tubing and a fluid source. A swivel joint is connected to one end of the pipe. The pipe is permitted to turn with the spool or is held stationary with respect to the stand depending on whether the swivel joint is mounted outside the stand or inside the spool.
