Coiled tubing well control equipment such as conventional four-ram/composite double-ram coiled tubing blowout preventers and blowout boxes produced by Douson 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. <br>
Until now, Douson has provided nearly 100 supporting products for several coiled tubing vehicle projects, making an important contribution to the localization of well control equipment for coiled tubing operations.

It is mainly used in the artificial lift oil production system to effectively control the internal pressure of the wellbore and prevent blowout. <br>
The sucker rod blowout preventer equipped with a special ram can clamp the pipe string, while sealing the pipe string and the annular space of the wellhead, it can also bear the weight and rotational torque of the downhole pipe string.

Important well control equipment during drilling. <br>
It can be used for killing wells, preventing combustion and fire, and assisting in fire fighting and other operations.

Offshore drilling manifolds are composed of choke manifolds, kill manifolds, cementing manifolds and standpipe manifolds. <br>
The choke and kill manifold is an important part of the well control system of the offshore drilling platform. <br>
The choke and kill manifold designed and installed according to the characteristics of offshore drilling operations has a vertical structure, high manifold pressure, and more safety redundancy.
