China's First Self-Run Deepwater Oil Field Cluster of Crude Oil Production Has Exceeded 10 Million Tons

China's first self-run deepwater oil group, Liuhua 16-2 ——, has produced more than 10 million tons of crude oil, according to China National Offshore Oil Corporation on June 8. As the most productive oil field group in the South China Sea, the annual peak output of 16-2 exceeds 4 million tons, and the crude oil produced can meet the annual gasoline consumption of more than 4 million family cars.

The Liuhua 16-2 oilfield group is located in the Pearl River Estuary Basin of the South China Sea, about 250 kilometers southeast of Shenzhen, including three oil fields: Liuhua 16-2, Liuhua 20-2 and Liuhua 21-2. The average water depth of the oil field group is 412 meters, which is the deepest offshore development depth in China. It has the largest underwater production system for offshore oil and gas fields in Asia, and the technical difficulty and complexity of development are among the highest in the world.

Jiang Junda, general manager of Liuhua Oilfield of CNOOC Shenzhen Branch, said that since the first oil field was put into operation in September 2020, the output of Liuhua 16-2 oilfield group has been increasing, and the current daily oil and gas output has remained above 11,000 tons of oil equivalent. All the production Wells of the oil field group are operating at full load, maintaining the external transmission frequency of "one ship of oil for 5 days and one ship of gas for 3 days". This year, the external oil and gas have been transported for 70 times.

It is worth mentioning that Liuhua 16-2 oil field group is in the deep water area, far offshore and complex equipment. When a typhoon strikes, it is necessary to evacuate personnel and shut down facilities, resulting in large production losses. This year, CNOOC Shenzhen Branch has implemented an automatic control system transformation on the oilfield group, making it the first deepwater oil field with remote control production capacity in China, which can maintain unmanned production during typhoons and ensure stable and high yield of the oilfield.

At present, offshore oil and gas has become an important growth pole of China's oil and gas production, and the deep sea with a water depth of more than 300 meters is the main replacement area for global oil and gas resources. It is understood that with the full production of Liuhua 16-2 oilfield group, China has explored and developed 12 oil and gas fields in deepwater waters in recent years, and the annual output of deepwater oil and gas exceeds 10 million tons of oil equivalent. The deep-sea oil and gas field is becoming an important force to ensure China's energy security.
