Bohai oilfield 1
Bohai Oilfield is the largest offshore oilfield in China and the largest crude oil production base in China. Tianjin Branch of CNOOC (China) Co., Ltd. is responsible for the exploration, development and production of Bohai Oilfield. Bohai Sea covers an area of 73,000 square kilometers, of which about 43,000 square kilometers can be mined.
2. Donghai Oilfield
An oil field located on the continental shelf of the East China Sea in China. The continental shelf of the East China Sea covers an area of about 460,000 square kilometers. Crude oil and natural gas were put into production at 1998 and 1999 respectively. By the beginning of the 20th century, eight gas fields such as Pinghu, Canxue, Broken Bridge, Baoyunge, Wuyunge, Tianwaitian, Xiao Chun and Peacock Pavilion, and oil-bearing structures such as Yuquan, Longer, Si Long and Gushan had been built.
3. Nanhai Oilfield
The oil fields in the eastern South China Sea stand at the forefront of the times, adhere to the drive of science and technology, and have the ability to independently explore and develop offshore oil and gas resources by introducing digestion and absorption, integrated innovation and independent innovation. The flexible application of high technology has brought remarkable economic benefits to some small oil fields and marginal oil fields.
Major Discovery in Bohai Oilfield
On March 18, 2020, China Offshore Oil Group Co., Ltd. announced that there was another major discovery in oil and gas exploration in Bohai Oilfield, the largest offshore oilfield in China. Well Kenli 6- 1-3, located in the north of Laizhou Bay in Bohai, drilled an oil layer with a thickness of about 20 meters, and it was proved that the annual output of crude oil in a single well could reach more than 400,000 barrels. This is the first large oil field in the north of Laizhou Bay.
On February 22nd, 2002 1 year, CNOOC China announced the proven geological reserves of Bozhong 13-2 oil field in Bohai Sea, which is another large-scale discovery of 100 million tons of oil and gas in Bohai Sea after Bozhong 19-6 obtained the 1000 billion cubic meter gas field. Bozhong 13-2 Oilfield is located in the middle of Bohai Sea, about 140 km away from Tianjin, with an average water depth of about 23.2 meters.
It is found that the oil layer drilled in Bozhong 13-2-2 is about 346m thick and the drilling depth is 5223m. After testing, the average daily output of this well is about 300 tons of crude oil and 6,543.8+0.5 million cubic meters of natural gas. The reservoir has the characteristics of light weight and high quality.
