LG360/60F车橇式连续管作业机的研制

Development of the LG360/60F Truck-skid CTU

LG360/60F车橇式连续管作业机是针对青海油田恶劣的自然环境和作业工况而专门研制的,整机底盘车越野能力强,采取不沉式底盘设计,重心较低,运行平稳,可靠性高。车上安装有可液压升降的控制室、下沉式可快换的连续管滚筒、动力及液压源系统及3个软管滚筒;顶吊式橇座,在运输时安装固定注入头、导向器、防喷系统及辅件等部件。它能够在干燥环境和风沙气候条件下连续作业。现场应用情况表明,该作业机在作业中,低速挡最大走管速度达到22m/min,下井深度1 452 m,设备运行与控制正常,达到了设计标准。

The LG360/60F truck-skid coiled tubing unit （CTU） is developed specially for the severe natural environment and operating conditions in Qinghai Oilfield. The chassis of the overall unit has a strong cross-country capacity. The unit adopts a sinking chassis design and low center of gravity with smooth running and high reliabili- ty. It consists of one truck and one skid. The hydraulically lifted control room, sinking quickly replaceable CT reel, power and hydraulic source system and three hose reels are installed on the truck. The fixed injector head, groose- neck, blowout prevention system and auxiliary parts are installed in the top lifting skid in transportation. It can work continuously in the dry environment and wind-sand weather conditions. The field application shows that the low gear of the unit reaches the maximum CT tripping speed of 22 m/rain in operation. The lowering depth is 1 452 m. The operation and control of the equipment are normal, reaching the design standard.
