The LXZ-5000 coiled tubing unit is a fully integrated, truck-mounted hydraulic operation system designed for efficient coiled tubing running, pulling, and well intervention services. It combines air, hydraulic, and electrical control systems into a single highly automated platform, offering reliable performance, precise control, and strong adaptability for complex oilfield operations. During operation, the coiled tubing is continuously spooled in and out of the reel and accurately injected into the wellbore through the injector system, enabling efficient and safe downhole intervention.
