COILED TUBING Boots & Coots 5238 Coiled Tubing Reel (Hydra Rig) The 5238 Hydra Rig coiled tubing reel is a DNV certified reel designed to store coiled tubing. The reel drum is supported on an axle and is rotated by a hydraulic motor. Levelwind To control the coiling process, a winding mechanism (levelwind) is synchronized with the rotation of the reel by a chain drive taken from the driveshaft. Should the spooling of the tubing not correspond to the drum rotation, an override operator control is provided in the control cabin. The levelwind arm can be lowered or raised from the cabin to help ensure that the tubing is kept at a proper angle to the injector head. Reel Swivel The inner end of the coiled tubing string is welded to a 3-in. hammer union. This union is attached to a plumbing arrangement inside the drum of the reel, with the last piece connected to the hub of the reel. To allow the circulation of fluids and gases into the tubing while running in or out of the hole, a high-pressure swivel joint is located at the end of the reel shaft. Any oilfield fluid or gas, such as acid or nitrogen, can be pumped through the connecting pipework, the swivel joint, and down the coiled tubing while the reel is in motion, and to any pressure up to 15,000 psi or coiled tubing operational limit. Depth Counters and Oiler system Electrical and mechanical depth odometers, mounted on the spooling arm, can be used. Their measuring wheels are rotated by frictional contact with the tubing as it passes by. Finally, an oiler system operated from the control cabin coats the coiled tubing with an oil-based corrosion inhibitor to help ensure long life. HAL40270 Hydraulic Drive The hydraulic drive system has a dual function. When uncoiling of the tubing (i.e. injecting into the well), the motor acts as a constant-torque brake keeping the tubing tight on the reel and tension between the reel assembly and injector head. When coiling the tubing (i.e. pulling out of the well), the motor is attempting to revolve the reel at a faster rate than the injector, thus increasing coiled tubing tension as it is spooled onto the drum.
