Abstract: CNPC Drilling Research Institute developed LG360/50 coiled tubing unit to satisfy the domestic demand for shale gas development. The whole unit is a two-truck-mounted structure in a self-propelled manner. The main vehicle chassis adopts a frame structure with the drum installed in a sunk manner. The capacity of the drum is ?50. 8mm while coiled tubing is 4800 meters long. Based on synergetic control over hydraulic system automation and key components as well as the study of control technology for ultra-low tripping-in stability of coiled tubing, the stable and reliable mechanics-electronics-hydraulics integrated technology is established to effectively improve automation level and operational safety of the whole control system. Currently, LG360/50 coiled tubing has been widely used on the field, thus promoting rapid development of coiled tubing technology in the shale gas development area and effectively improving China’s coiled tubing engineering technological service capacity.
