Abstract
The LG380/60 coiled tubing unit (CTU) is developed specially for the severe natural environment and operating condi-tions based on the designed LG230 CTU. The CTU adopts the twin truck-mounted self-propelled scheme. It consists of the hydraulically lifted control room, sinking quickly replaceable CT reel, three hose reels, blowout prevention system, injector head and hydraulic gooseneck. The chassis of the overall unit has a strong cross-country capacity. The beam of the chassis with variable cross section is customized. So a sinking chassis design is adopted to increase the capacity of the CT reel. The hydraulic system which is of structural simplicity and high reliability can realize the linkage control of the injector head and CT reel. The control system has functions of human-computer interaction and CAN communication. In addition the unit is equipped with the wellhead anti-collision device to reduce the risk. It has such strengths as strong lifting capacity, large reel capacity, desirable transportability, and extensive applicability. The field application shows that the low gear of the unit reaches the maximum CT tripping speed of 25 m/min in operation. The lowering depth is 3 134 m. The operation and control of the equipment are normal,reaching the design standard.关键词
