Bohai oilfield - Offshore BOP group project

The 13-5/8"-5000psi blowout preventer group developed and designed by Douson is applied to the Lvda 21-2 oilfield in Bohai Oilfield. The blowout preventer group delivered by Douson was applied to the first heavy oil thermal recovery platform in China for the first time, fully proving the applicability, safety and reliability of Douson's well control equipment in various working conditions. BOP groups are distributed on three platforms: LD16-3, LD16-3S, and LD21-2. The oilfield is located in the Liaodong Bay area of the Bohai Sea. The drilling and completion methods of the three platforms are "drilling and completion with jack-up drilling platform + workover with HXJ180 workover rig + drilling adjustment wells with jack-up drilling platform".

The blowout preventers produced by Douson have complete specifications, which can meet the needs of various operations such as drilling and workover, and have been successfully used in domestic and foreign major land oilfield projects and offshore platform drilling project.
