coiled tubing unit for efficient well intervention

The Coiled Tubing Unit

The coiled tubing unit is a highly integrated and modern oilfield equipment that combines pneumatic, hydraulic, and electronic control systems. It features a complex structure and a high level of automation. The coiled tubing unit is primarily used for transporting coiled tubing and facilitating its insertion and retrieval during downhole operations. In practice, the coiled tubing can be repeatedly wound and unwound on the drum of the unit, and is smoothly injected into the wellbore through the injector head to perform various downhole tasks.

Key Features of Coiled Tubing Unit

• The dual-vehicle split design greatly enhances on-site operational flexibility and mobility, making it suitable for complex terrains and harsh road conditions.
• The main vehicle adopts a high-strength frame beam structure, which significantly improves the overall load-bearing capacity and ensures stable operation under heavy loads.
• Equipped with a large-capacity coiled tubing drum, it supports the deployment and retrieval of 2-inch and larger diameter coiled tubing, and the integrated design allows for easy and safe drum replacement.
• A reserved backup system for blowout preventers (BOP) is provided to meet the requirements of dual BOP operations, enhancing well control safety.

Application Fields

The coiled tubing unit is widely used in various stages of oil and gas field operations, including drilling, well intervention, and completion. Its scope of work covers not only conventional tasks such as sand washing and simple well servicing, but also more complex operations like cementing, fishing, logging, reaming, scale removal, and completion. In addition, the equipment is suitable for unconventional oil and gas development and the implementation of special downhole processes, making it an essential tool for improving operational efficiency and safety in modern oilfields.
