The only one in the world!Severe many world problems!Breakthrough 200 million tons

China Sea Oil announced on the 29th that in the 30 years since the development of Liaodong Bay in the Bohai Oilfield, a total of 200 million tons of oil and gas production have exceeded 200 million tons.

Liaodong Bay is the highest latitude area in my country. It has abundant oil and gas resources. It has accumulated a total of more than 800 million tons of petroleum geological reserves, and natural gas geological reserves exceed 70 billion cubic meters. At present, the Bohai Oilfield has built a total of 68 offshore oil mining facilities and three land terminal plants in Liaodong Bay, with more than 1,300 oil -water wells that are put into production. 200 million tons, equivalent to 40 years of oil and gas usage in a 10 million population cities in my country.

Li Chunyong, Liaodong Operations Company of China Oil Tianjin Branch, said that many technical difficulties have been overwhelmed in Liaodong Bay oil and gas development, and have developed a number of hundreds of millions of tons of oil fields such as 36-1, Jinzhou 25-1 South 10 million tons, formed a number of key technologies for the development of maritime oil fields.

In 1992, the production of the 20-2 gas field of Jinzhou, the northernmost gas field in my country, opened the prelude to the development of oil and gas development in Liaodong Bay. In September 2020, the successful operation of the 21-2 oil field of the University of Travel means that my country has achieved the large-scale development of thick oil at sea. In the next three years, Liaodong Operations Company will have multiple new oil fields to put into operation to achieve shore electricity connected to Suizhong 36-1 oilfield and Jinzhou 25-1 Nando Gas Power Grid.

Liaodong Bay oil and gas development overcome many world problems

Liaodong Bay has a three -month freezing period in the year, while thick oil resources are very rich. Thick oil is a crude oil with poor liquidity. The Bohai Oilfield has overcome many world problems on "ice anti -ice technology" and "thick oil thermal mining technology".

Sea Ice is formed by the frozen seawater, and it is called the five major disasters of the ocean with the tsunami, storm waves, disaster waves and red tide. Sea ice is known as "white killer", and the Bohai Sea is iced every year. The lowest temperature in the Liaodong Bay in winter reaches minus 30 ° C, the maximum thickness of the sea ice is 60 cm, and the mining of marine oil and gas is extremely difficult.

Luo Shaofeng, director of Liaodong Operations Company of China Oil Tianjin Branch, said that in order to safely minimize oil and gas in the ice area, we created the only pile base box -type multi -functional ice -resistant platform in the world, and through the platform breaking ice boat ice, platform pile legged innovation Design, forming a world -leading ice area production management technology system.

Thick oil development is another major breakthrough in oil and gas development in Liaodong Bay. Under the temperature of thick oil, it is buried underground like a black amber. With the lack of space on the sea platform, the effective experience of land cannot be simply reference, and the exploitation is extremely difficult. Through the breakthrough of thick oil steam thermal mining technology, China Oil, in 2021, the annual output of thick oil in the Bohai Oilfield has exceeded 300,000 tons for the first time.

In April 2022, the world's first ultra-thick oil-scale development oil field-the completion of the 5-2 Northern Oilfield of Journey to the University of China, marking that my country's maritime oil development technology has reached the world-class level. During the "14th Five -Year Plan" period, Liaodong Bay planned to use unconventional thick oil geological reserves of 170 million tons, and the annual output scale reached 3 million tons.
