my country's "Deep Sea No. 1" large gas field has a cumulative gas production of over 8 billion cubic meters. After the second phase of the project is put into operation, the annual output is expected to increase by another 50%.

According to this site’s news on May 3, CNOOC released news on May 2, announcing that the ultra-deepwater gas field “Shenhai No. 1” has maintained high and stable production, and the cumulative gas production has exceeded 8 billion cubic meters, equivalent to the annual gas consumption of 4 million households; produces more than 800,000 cubic meters of condensate , continuing to maintain its position as the main gas field in South China that guarantees supply "from sea to land".

#The "Deep Sea No. 1" large gas field is located in the southeastern waters of Hainan Island and has proven natural gas. The reserves exceed 100 billion cubic meters, the maximum water depth exceeds 1,500 meters, and the maximum well depth reaches more than 4,000 meters.

The gas field was officially put into production on June 25, 2021, and operates the world's first 100,000-ton deepwater semi-submersible production and oil storage platform independently designed and built in my country - the "Deep Sea No. 1" energy station.

The offshore operation team of CNOOC's "Deep Sea No. 1" large gas field has explored and established a complete technical system for deepwater gas field production and operation and maintenance, which has solved many problems such as deepwater underwater liquidity guarantee and many other problems for the safe and stable production of the gas field. There are industry problems that have an impact. It is recommended that the gas field reach the peak of the designed production capacity in the year it is put into operation and has been maintained in good operating condition, complete the remote production transformation of the semi-submersible platform and build a digital twin model, and recommend the in-depth application of intelligent digital technology in the field of deepwater oil and gas development.

Currently, the construction of the second phase of the "Deep Sea No. 1" project is being stepped up. After the new project is put into operation, the overall peak annual output of the "Deep Sea No. 1" large gas field is expected to increase by another 50%, becoming an important gas source for ensuring my country's national energy security.

The above is the detailed content of my country's "Deep Sea No. 1" large gas field has a cumulative gas production of over 8 billion cubic meters. After the second phase of the project is put into operation, the annual output is expected to increase by another 50%..
