The Coiled Tubing Truck (Truck-Mounted Coiled Tubing Unit) is a highly integrated, self-propelled well-intervention workover equipment designed in compliance with API RP 5C7 petroleum industry standards. Integrating truck chassis, injector head, large-capacity tubing reel, BOP well-control stack, hydraulic-pneumatic-electric control system and enclosed operator cabin, this full-series unit covers multiple pulling-force grades for shallow, medium and deep-well service. Without killing the well, continuous coiled tubing can be run in and pulled out rapidly through injector-head chain clamping mechanism to fulfill diverse downhole operations. It undertakes core jobs including sand washing, paraffin removal, nitrogen lifting, acidizing stimulation, plug milling, fishing and wellbore cleanup. Adopting vehicle-borne modular layout, the equipment features good cross-country mobility and fast rig-up at well-site, eliminating repeated tripping of conventional jointed tubing. Optimized for full-climate harsh oilfield conditions, coiled tubing truck provides efficient, safe and reliable mobile well-intervention solutions for on-shore oil-gas well workover, completion stimulation and cluster-well batch construction projects.
The product portfolio covers light-duty, medium-duty and heavy-duty grades with continuous pulling force ranging from 180 kN up to 450 kN. Adopts heavy-duty all-wheel-drive truck chassis for complex road and wilderness well-site access. Single-truck or split dual-truck configurations are optional, supporting fast transportation and short rig-up time, greatly reducing auxiliary preparation cycle for field operations.
Core injector-head adopts dual high-torque hydraulic motor and heavy-duty chain-gripper assembly. Real-time weight-sensor feedback realizes stable low-speed feeding and pulling, avoiding tubing squeezing, slipping or buckling damage. The tubing reel is equipped with automatic pipe-arranging mechanism and closed-loop constant-tension hydraulic system, keeping proper back-tension during spool-in / spool-out for neat coiling and extending coiled-tubing service life.
Matched with full-set BOP stack including pipe ram, shear ram, blind ram and stripper assembly, meeting high-pressure live-well intervention safety requirements. Multi-layer safety interlock covers overload protection, over-speed protection, anti-jamming auto-stop and emergency shutdown function. All well-control assemblies strictly comply with API well-control specifications to eliminate blow-out risks during live-well operations.
Human-machine integrated enclosed operator cabin realizes one-place centralized operation. Real-time monitoring of pulling force, snubbing force, running depth, system pressure and tubing speed; built-in data acquisition module supports operation-data storage, playback and export for traceable job records. Manual-automatic dual-control mode improves operational flexibility and fault-tolerance for complex downhole conditions.
Hydraulic, sealing and electrical components adopt wide-temperature adaptive configuration. Heavy-duty anti-corrosion sand-proof coating for whole vehicle. Reliable continuous operation is available within -40 ℃ ~ +55 ℃, perfectly adapting to desert high-temperature, Gobi wind-sand, muddy well-sites and high-altitude cold plateau oil-field environments.
Key assemblies including injector head, reel and well-control manifold adopt standardized modular design. Wearing parts and sealing elements enjoy high interchangeability. The layout facilitates daily inspection, lubrication and component replacement, cutting down field downtime and comprehensive operation-maintenance expenditure.

The following questions address common equipment selection and operating considerations.
Coiled tubing truck can perform live-well intervention without killing well, avoiding reservoir damage caused by kill-fluid invasion. It eliminates frequent make-and-break of threaded tubing joints, greatly improves operating efficiency and shortens construction cycle. Vehicle-borne integration realizes fast transfer and rig-up, especially suitable for frequent well-service tasks in cluster-well blocks.
The complete API-compliant BOP well-control stack serves as primary well-barrier. Injector-head and reel systems are equipped with multi-level interlock protections including overload, anti-jamming auto-stop and emergency shutdown. Real-time monitoring of pulling-force and system pressure helps operators respond promptly to abnormal downhole events.
Main factors include maximum expected downhole pulling-snubbing load, target well depth, outer-diameter of selected coiled tubing, wellhead working-pressure and local road-transport constraints. Light-duty units fit shallow well routine maintenance; heavy-duty grades serve deep-well plug-milling and heavy-fishing assignments.
