摘要:
针对国内油田复杂的作业环境及实际作业需求,在成功研制的LG230连续管作业机的基础上,开发了LG380/60大直径连续管作业机。该作业机主要包括可升降操作室、可升降油管滚筒、软管滚筒工作组、井口防喷装置、大提升力注入头以及动力鹅颈管等部件。该作业机底盘采用变截面大梁结构,油管滚筒能够下沉安装,满足滚筒大容量的要求;液压系统组成简单、可靠性高,提高了注入头与油管滚筒联动性;自动控制系统具有CAN通信和人机交互功能。同时,还配备井口防碰装置,降低作业风险。整机提升能力强,适应管径大,滚筒容量大,移运性能好,适应性广。现场作业情况表明:该设备低速档最大速度达到25 m/min,下井深度3 134 m,整套设备运转正常,各指标与设计值相符。
Abstract:
The LG380/60 coiled tubing unit (CTU) is developed specially for the severe natural environment and operating conditions 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.
