China's Largest Offshore Oilfield Reaches 100 Million Tons of Cumulative Crude Oil Production

TapTechNews June 23 - According to the report of CCTV News today, the cumulative production of crude oil at China's largest offshore self-operated oilfield, Suizhong 36-1 Oilfield, has exceeded 100 million tons, becoming the first offshore oilfield in China to produce more than 100 million tons of crude oil.

It is reported that the Suizhong 36-1 Oilfield is located in the northern part of the Bohai Bay. It was put into production in 1993, and the peak annual output of crude oil exceeded 5 million tons. The cumulative proven petroleum geological reserves exceeded 300 million tons. Currently, it has 24 platforms, and the daily output of crude oil exceeds 8900 barrels. It is the main oilfield of the Bohai Oilfield, which is the largest crude oil production base in China.

Zhang Chunsheng, the deputy general manager of Tianjin Branch of CNOOC, said:

100 million tons of crude oil is equivalent to half of China's crude oil production in 2023 and can be used by the population of a large million-level city for about 20 years, which has important implications for ensuring national energy security, promoting national economic development, and meeting the needs of people's lives.

TapTechNews learned from the report that the Suizhong 36-1 Oilfield is located at 40 degrees north latitude in an ice area and is a heavy oilfield that is more difficult to exploit. The exploitation faces the dual challenges of the freezing period and the poor fluidity of crude oil. It was once described by foreign experts as a challenge to the new technologies of the 21st century. The technical personnel pioneered water injection and forced production technology for heavy oil development and carried out technological introduction and innovation in process, sand control and other aspects to overcome this world-class technical problem of offshore heavy oil development.
