China News Service, Beijing, September 9th (Reporter Wang Enbo) The reporter learned from China National Offshore Oil Corporation ("CNOOC") on the 9th that the world's first intelligent deepwater drilling platform "Deep Blue Exploration" independently designed and built by China The successful drilling of the Pearl River Mouth Basin in the South China Sea marked a substantial step forward in the development of China's intelligent deepwater oil and gas equipment.
The exploratory well drilled in this "Deep Blue Exploration" is about 230 kilometers southeast of Hong Kong, China, with a water depth of 370 meters, and is close to the Liuhua 16-2 oilfield group, the first self-operated deepwater oilfield group in China.
Zhang Weiguo, general manager of the Deepwater Engineering Technology Center of CNOOC Shenzhen Branch, said that "Deep Blue Exploration" is the world's latest semi-submersible drilling platform "tailored" for the South China Sea deepwater oil and gas exploration and development. It adapts to the South China Sea culture and climate environment. It can be the important task of oil and gas exploration and development in the middle-deep water area, high-temperature and high-pressure strata, and ultra-deep buried strata in the South China Sea.
It is understood that the platform has a maximum operating water depth of 1,000 meters and a maximum drilling depth of 9,144 meters. It integrates the performance advantages of a traditional anchored drilling platform and a modern dynamic positioning platform. It is the world's first drilling rig to obtain the DNV intelligent certification. platform.
Zhou Songmin, general manager of COSL Drilling Division, told reporters that "Deep Blue Exploration" is equipped with a brand-new self-developed "intelligent operation and maintenance system" platform, which has intelligent integration functions of "perception, analysis, and decision-making", which can collect production operation and maintenance data in real time to achieve Cloud processing, remote collaboration and optimized decision-making.
The platform is equipped with an intelligent blowout preventer system, which can automatically cut and close in extreme cases to ensure safety and reliability.
The platform can realize the simultaneous operation of main and auxiliary wellheads. Compared with the conventional single wellhead mode, the overall operation efficiency can be increased by 35%. The inclusion of this platform further enhances China's oil and gas exploration and development capabilities in medium and deep waters.
At the same time, "Deep Blue Exploration" also adopts the world's highest-strength anchor chain and related mooring equipment independently developed by China, which can effectively respond to severe sea conditions and the threat of super typhoon, adapt to global sea operations, and is especially suitable for oil and gas exploration and development in the South China Sea.
