China's largest oil production plant has produced 200 million tons of oil, which is enough for 10 million people to use for 40 years

China's largest oil production plant has produced a total of 200 million tons of

On August 29, China National Offshore Oil Corporation (hereinafter referred to as CNOOC) announced that as of now, its Bohai Oilfield Liaodong Operation Company has produced 200 million tons of crude oil in the past 30 years, which is equivalent to about 40 years of use by

Liaodong Bay is the highest latitude sea in China and is rich in

Daqing Oilfield No.

Bohai Oilfield Liaodong Operation Company is affiliated to Bohai Oilfield

Since the Jinzhou 20-2 gas field was put into operation in 1992, the Liaodong Operation Company of Bohai Oilfield has successively developed a number of 100 million-ton oilfields such as Suizhong 36-1 and Jinzhou 25-1 South, as well as Luda 21-2 Oilfield and Luda 5-2 North Oilfield

Liaodong Bay has a three-month freeze period a year, with a minimum temperature of minus 30 in winter and a maximum thickness of 60 centimeters

In order to safely exploit oil and gas in the ice area, CNOOC has created the world's only "pile-based caisson-type multi-functional anti-icing platform", and established a scientific management system for preventing sea ice hazards, forming a world-leading ice area production management technology system, and ensuring the safe production

In 1993, the Suizhong 36-1 oilfield in Liaodong Bay, the largest self-operated oilfield in China's offshore sea, was explored and discovered, but the oilfield was heavy oil, which was
difficult to explore and develop.

Bohai Oilfield opened a test area for heavy oil, pioneered the development technology of water injection and strong production of heavy oil, and later developed chemical flooding technology, and finally achieved an annual oil production of more than 3 million tons, with a cumulative oil production of nearly 100 million tons
.

Li Chunyong, general manager of Liaodong Operation Company, said that in order to promote the use of more and thicker reserves, the company will lock the power point of reducing the viscosity of heavy oil on
hot recovery.

In September 2020, China's first large-scale heavy oil thermal recovery project, Luda 21-2 Oilfield, was successfully put into operation
.
In April 2022, the world's first offshore super heavy oil large-scale development oilfield, Luda 5-2 North Oilfield, was completed and put into operation, marking that China's offshore heavy oil development technology has reached the world-class level
.

CNOOC said that in the next three years, Liaodong Operation Company will have new oilfields put into operation one after another, and will also realize shore power access to the Suizhong 36-1 oilfield and Jinzhou 25-1 south oil and gas field power grid
