my country's first self-operated deep-water large gas field "Shenhai No. 1" was completed and put into production

It was learned from CNOOC on the 25th that the first 1500-meter ultra-deep water large gas field "Deep Sea One" developed by China's self-operated exploration and development was formally put into production in the south of Lingshui area of ​​Hainan Island, marking that CNOOC's exploration and development capabilities have fully entered the "extra" area.
The Deepwater Era"
.

The "Deep Sea No.
1" large gas field is 150 kilometers away from Sanya City, Hainan Province.
It was discovered by exploration in 2014.
The proven geological reserves of natural gas exceeded 100 billion cubic meters, the maximum water depth was more than 1,500 meters, and the maximum well depth was more than 4,000 meters.
Discovered offshore ultra-deep water gas fields with the deepest water depth and the most difficult exploration and development
.

After the gas field is put into production, deepwater natural gas will be connected to the national natural gas pipeline network through submarine pipelines, and will provide a steady supply of 3 billion cubic meters of gas to Guangdong, Hong Kong, Qiong and other places each year, which can meet a quarter of the residential gas demand in the Guangdong-Hong Kong-Macao Greater Bay Area.
The natural gas supply capacity in the South China Sea has increased to more than 13 billion cubic meters per year, which is equivalent to 2.
6 times the annual gas consumption of Hainan Province
.

CNOOC Chairman Wang Dongjin said that the successful development of the "Deep Sea No.
1" large gas field has made a major breakthrough in China's deepwater oil and gas development capabilities and deepwater offshore engineering equipment construction level, marking that China has fully grasped the "key" to open the South China Sea deep sea energy treasure.
, To achieve a historic leap forward from 300 meters to 1500 meters ultra-deep water
.

　　In order to efficiently develop the "Deep Sea No.
1" large gas field, CNOOC adopted the all-sea development model of "semi-submersible production platform + underwater production system + submarine pipeline", and tailor-made the world's first 100,000-ton level Deepwater semi-submersible production and storage platform-"Deep Sea No.
1" energy station
.

　　According to You Xuegang, the general manager of the "Deep Sea No.
1" large gas field development project, the energy station is designed according to the high standard of "30 years without back-to-docking for overhaul", with a design fatigue life of 150 years, which can withstand super typhoons that occur once in a hundred years
.

　　The completion and commissioning of the "Deep Sea No.
1" energy station can drive the development of new deep-water gas fields such as Lingshui 25-1 in the surrounding area, forming a cluster of gas fields.
Relying on the established natural gas pipeline network connecting the Guangdong-Hong Kong-Macao Greater Bay Area and the Hainan Free Trade Port, Maximize the development, production and transmission of natural gas resources
