Three pulling ratings define this coiled tubing line: ZLG155/38 holds 155 kN continuous tension, ZLG225/45 holds 225 kN and ZLG290/50 holds 290 kN, with laying depths of 3600, 4200 and 5900 m on 1.5-inch tubing. Each reel stores 3800, 4500 or 6100 m of continuous string, forced down by 75, 115 or 145 kN of injector push at up to 60 m/min, so the well is worked live without tripping jointed pipe. That tripless intervention is the point: sand washing, paraffin removal, nitrogen lifting, acidizing, plug milling and fishing all run on one continuous conduit, which is why cluster-well and completion-stimulation spreads put a CT unit on the light-to-medium deep-well window instead of a conventional workover rig.
The ZLG155/38, ZLG225/45 and ZLG290/50 ratings let a spread match pulling force to depth rather than over-spec the reel: 155 kN for shallow intervention and 290 kN for the 5900 m window. The tension ladder is what sets model selection against the well's measured depth.
Maximum laying depth runs 3600, 4200 and 5900 m across the three models on 1.5-inch tubing, while each reel carries 3800, 4500 or 6100 m of string. Because the conduit is continuous, that depth is reached without a single pipe connection, which is the time saved on sand-wash and acid runs.
The injector head does not rely on gravity to run: forced laydown of 75, 115 or 145 kN pushes tubing into deviated or pressurized holes. That push capability is what makes live-well snubbing possible rather than waiting for the well to be killed.
Lifting speed holds at 60 m/min across the range, so a 4500 m reel is pulled in or out on a predictable clock. The constant feed rate also matters for milling and cleanout runs where speed variation would leave uneven fill.
A BOP stack and injector head ride as part of the truck package, sized to the working pressure of the 155/225/290 kN class. Intervention proceeds on a pressurized well, which removes the cost and formation damage of a kill job.
Tubing diameter is set per model, from 1 to 1.5 inch on the 155 class to 1.5 to 2 inch on the 290 class, so flow area and pull capacity stay balanced for acid, nitrogen or fill-removal duty.

Buyers evaluating the coiled tubing truck usually ask about depth reach, tubing size and injector rating.
The unit intervenes on a live well without a kill job, so the formation is not exposed to kill-fluid invasion. Because the conduit is one continuous string, there is no make-and-break of threaded joints between runs: the reel holds 3800, 4500 or 6100 m of tubing and the injector feeds it at up to 60 m/min, which cuts rig time on sand-wash, acid and plug-milling runs. The truck carries injector, reel and BOP as one load, so it drives between cluster-well pads and starts working after hose-up rather than module rig-up.
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.
Yes. Standard version supports operation from -40 ℃ to +55 ℃. Optional low-temperature hydraulic oil circuit and heating assembly guarantee reliable cold-start and continuous operation for frigid plateau and winter well-site conditions.
Yes. The configuration is settled against the well-intervention programme before the order: continuous-tension grade (155, 225 or 290 kN), reel capacity, tubing diameter, BOP working-pressure class, chassis scheme and monitoring package are matched to target depth, regional road-transport limits and the planned live-well operations, then written into the quotation and the factory test report.

A boiler truck earns its keep by heat, not by pressure: this unit delivers working water at up to 280 through a fired tube package rated at 6 or 9.8 MPa, at a hot-water or steam output of 1.26, 1.8 or 3.0 t/h.
The swabbing unit is rated by a drum-dependent lifting envelope: up to 120 kN at minimum drum diameter, down to 80 kN as the drum fills, with a maximum working depth of 3350 m.
This unit combines two duties in one truck: a triplex plunger pump rated up to 35, 40 or 70 MPa at 50, 60, 80 or 100 m3/h for cold high-pressure flushing, and a fired heater that delivers hot wash at 20 MPa and 160, at…
