Coiled tubing well control equipment such as conventional four-ram/composite double-ram coiled tubing blowout preventers and blowout boxes produced by BestRig  are equipped on the coiled tubing operation vehicles of many oil service companies and oil fields. The rams of the tubing blowout preventer are suspended/semi-sealed, sheared/full-sealed rams, which greatly reduce the weight and height of the equipment and meet the requirements of operating conditions while meeting the requirements of technology and functions.
