  • Patent number: 10329858
    Abstract: The present invention relates to the field of petroleum extraction equipment, and discloses a coiled tubing unit, which comprises a vehicle body (T), a control cab (30), a coiled tubing reel (10) configured to wind coiled tubing, and a power skid (20) configured to supply power to the coiled tubing reel (10) and transported separately, wherein, the coiled tubing reel (10) and the control cab (30) are mounted on the vehicle body (T). With the coiled tubing unit provided in the present invention, the total length and total weight of the vehicle body on which the coiled tubing reel is mounted are smaller and can meet the requirements for transportation in regions where smaller vehicle dimensions and weight are specified for transportation when coiled tubing in large diameter and/or great length is transported, and the coiled tubing unit is adaptive to the operating habits, and can be deployed flexibly so that it can be used in a well field where the space is limited.
