Original title: Bohai Oilfield’s annual output of crude oil exceeds 30 million tons, becoming China‘s largest crude oil production base
China News Service, Beijing, January 9th (Reporter Wang Enbo) CNOOC announced on the 9th that China’s largest offshore oil field, the Bohai Oil Field, will produce 30.132 million tons of crude oil in 2021, making it China’s largest crude oil production base with an increase in crude oil. It accounts for nearly 50% of the national increase.
Founded in 1965, Bohai Oilfield is the birthplace of China‘s offshore oil industry, and it is also the main oilfield with the highest output, the largest scale and the best benefits carefully cultivated by China National Offshore Oil Corporation. Over the past 50 years since it was put into operation, it has discovered proven oil reserves of over 4.4 billion tons and natural gas reserves of nearly 500 billion cubic meters, contributing more than 493 million tons of oil and gas to China.
Since CNOOC fully implemented the “Seven-Year Action Plan” for increasing oil and gas reserves and production in 2019, Bohai Oilfield has continuously discovered four Bozhong 19-6, Kenli 6-1, Kenli 10-2 and Bozhong 13-2. The 100 million-ton oil and gas field has produced 85.353 million tons of crude oil and 9.15 billion cubic meters of natural gas in three years. At present, the oil field has more than 50 producing oil and gas fields and more than 180 production facilities. It has established a comprehensive oil and gas production base covering three provinces and one city in the Bohai Rim, integrating exploration and development, engineering construction, and production and operation.
According to Xue Yongan, Chief Exploration Officer of CNOOC Tianjin Branch, the geological structure of the Bohai Bay Basin is complex, like a “golden plate.” There is also a layer of sea water, making exploration and development more difficult.
In order to find these scattered oil reservoirs, Bohai Oilfield has successively applied the concepts of “three-dimensional exploration”, “cluster exploration”, “combined exploration” and “value exploration”, and the proven reserves have continued to rise. After entering the “Thirteenth Five-Year Plan” period, Bohai Oilfield has innovatively proposed the theory of “lake basin gas formation” and “convergent ridge” accumulation theory, and discovered several hundred million-ton oil and gas fields, which lays a solid foundation for building China‘s largest crude oil production base. Reserve basis. During the “14th Five-Year Plan” period, Bohai Oilfield will also work hard to ensure that 40 million tons of oil and gas production will be achieved by 2025.
As the largest offshore oil and gas producer in China, CNOOC has ranked first among the three major oil companies in terms of domestic crude oil production growth for three consecutive years. In 2021, the company will produce 48.64 million tons of crude oil in China, a year-on-year increase of 3.23 million tons, accounting for about 80% of the total increase in domestic crude oil. (Finish)
