Oil Prices Soar! China's Largest Oil Field Adds 140 Million Tons

Recently, with the changes in the international situation, international oil prices have been soaring, from more than 70 US dollars at the beginning of the year to a high of 90 US dollars! As China's largest crude oil production base, the Bohai Oilfield has also continued to make efforts. Not only has it added more than 40 million cubic meters of proven oil and gas reserves in the 100-million-ton oil field Bozhong 26-6 Oilfield, it has also added more than 40 million cubic meters of proven oil and gas reserves in the central and northern waters of the Bohai Sea. A major oil discovery of 100 million tons was made - Qinhuangdao 27-3 Oilfield, with proven oil geological reserves of 104 million tons! This means that 144 million tons of oil and gas were discovered in one month!
1. The world's largest metamorphic rock oil field, exceeding 200 million tons
The Bozhong 26-6 oil field located in the middle of China's Bohai Sea is the world's largest metamorphic oil field.
In recent years, Bozhong 26-6 Oilfield has made major breakthroughs in exploration. On February 25, the newly added proven geological reserves of oil and gas exceeded 40 million cubic meters, and its cumulative proven reserves have exceeded 200 million cubic meters, making it the world's largest metamorphic oil field.
The Bozhong 26-6 oil field is located in the southern waters of the Bohai Sea, about 170 kilometers away from Tianjin. The reservoirs of oil fields are buried in buried hills thousands of meters deep under the sea and are mainly composed of metamorphic rocks, which makes their exploration and development quite technically difficult. Through scientific and technological research, CNOOC's scientific researchers innovatively proposed the theory of deep oil and gas exploration in extension-strike-slip composite fault zones, independently developed ultra-low frequency all-round seismic exploration technology, overcame problems such as deep seismic imaging of complex fault zones, and finally successfully discovered this 100-million-ton oil field.
According to normal recovery calculations, the crude oil that can be extracted from the oil field, after being refined into gasoline, can meet the daily transportation needs of urban residents with a population of one million for more than 20 years; the natural gas that can be mined can meet the household gas needs of urban residents with a population of one million for more than 60 years. This achievement is of great significance for ensuring national energy security and promoting economic and social development.
The discovery of the Bozhong 26-6 oil field not only demonstrates China's strong strength in deep oil and gas exploration, but also injects new impetus into the sustainable development of China's crude oil industry. At the same time, the discovery of the Bozhong 26-6 oil field has also provided new ideas and directions for the exploration and development of metamorphic oil fields around the world.
With the continuous growth of global energy demand and the gradual depletion of traditional oil and gas resources, the exploration and development of unconventional oil and gas resources such as metamorphic rock oil fields will gradually become an important development direction in the future energy field. Therefore, the successful experience and technological innovation of the Bozhong 26-6 Oilfield also have a profound impact on the global energy industry.
2. A billion-ton oil field, and another billion-ton oil field in ten years' time
On March 18, my country's central and northern Bohai Sea made another 100-million-ton discovery - the Qinhuangdao 27-3 oil field, with proven oil in place reserves of 104 million tons. This is the first major oil and gas discovery in this area in 10 years. It is of great significance to further consolidate my country's offshore oil and gas resource reserves and ensure national energy security.
Qinhuangdao 27-3 Oilfield is located in the north-central Bohai Sea, about 200 kilometers away from Tianjin City, with an average water depth of about 25 meters. After in-depth exploration, scientific researchers found that the oil field has broad exploration prospects, with the daily crude oil production of a single well reaching about 110 tons.

Zhou Jiaxiong, deputy general manager of CNOOC Tianjin Branch, said that the crude oil production volume of Qinhuangdao 27-3 oil field is expected to reach nearly 20 million tons. After being refined, these crude oils can meet the daily transportation oil needs of urban residents with a population of one million for more than 10 years. At the same time, the extracted asphalt can also be used to pave more than 100,000 kilometers of four-lane highways, which is equivalent to circling the earth more than three times.

It is worth mentioning that the discovery of Qinhuangdao 27-3 oil field is an important practical result of the Bohai Sea shallow lithology exploration idea. Scientific researchers drew on the successful experience of previous billion-ton lithological oil fields and shifted the exploration focus from traditional structural exploration to lithological exploration. Through in-depth analysis of a large amount of drilling data and experiments, scientific researchers successfully proved that the lower parts of the area also have the ability to store oil and gas, breaking the limitations of traditional understanding.

Xu Changgui, deputy chief engineer of CNOOC Exploration, said that the discovery of the Qinhuangdao 27-3 oil field not only further confirmed the rich oil and gas resource potential of the complex strike-slip fault zone in the Bohai Sea, but also marked that the Bohai Oilfield has successively obtained multiple billion-ton oil fields in recent years. major discoveries.
This achievement will inject new vitality into the development of my country's offshore oil fields, and is of great significance to stabilizing my country's energy rice bowl and assisting the coordinated development of Beijing, Tianjin and Hebei.
