Get rid of the new China’s "poor oil" hat and create a miracle of stable production of similar oil fields in the world … … On the 26th, the cumulative crude oil production of Daqing Oilfield of China Petroleum, the largest onshore oilfield in China, exceeded 2.5 billion tons, accounting for 36% of the total onshore crude oil production in China. Over the past 60 years, Daqing Oilfield has formed the world’s leading development technology of continental sandstone oilfield, and has been constantly carrying out new practices to secure the energy rice bowl.
Old oil fields are still creating new miracles.
Songnen Plain, the towering derrick of the 1205 drilling team, and the words "Iron Man Team Forever" are eye-catching. The 1205 drilling team was led by Iron Man Wang Jinxi. "Old captain ‘ Iron ’ Style inspires us to lay a good job in every well. " Zhang Jing, captain of the 1205 drilling team, said.
Since the development and construction of Daqing Oilfield, it has provided surging kinetic energy for China’s economic giant. Filling 2.5 billion tons of crude oil with a 60-ton tanker can circle the equator 15.6 times.
Back in time, on September 26, 1959, the third well of Songji in Songnen Plain liked to spray industrial oil flow, and a large oil field was discovered in the northeast. On the eve of anniversary, the 10th anniversary of the founding of New China, anniversary Oilfield got its name.

"The north wind is an electric fan, and the heavy snow is fried noodles. The south China sea and the north China sea came to battle and vowed to win the number one oil field. Fuck! Fuck! Fuck! " Iron man’s poem is a vivid footnote to the big battle of swallowing mountains and rivers and oil. Tens of thousands of battle troops, with the spirit of "if conditions permit, they should also go if conditions are not created", let New China get rid of the "poor oil" hat in one fell swoop, and the picture of the Iron Man stirring mud with his body to stop the blowout is fixed in the memory of several generations of Chinese.
In 1976, the annual output of crude oil in Daqing Oilfield jumped to 50 million tons for the first time. Compared with the development of similar oil fields in the world at that time, the short-term stable production was 3 to 5 years and the long-term stable production was 10 to 12 years.
How long can Daqing Oilfield keep stable production?
Wu Xiaolin, chief technical expert of Daqing Oilfield, said that from 1976 to 2002, Daqing Oilfield achieved a high and stable yield of more than 50 million tons of crude oil for 27 consecutive years, creating a miracle in the development history of similar oilfields in the world.
Since 2003, the annual output of oil and gas equivalent in Daqing Oilfield has always remained above 40 million tons, and the old oilfield still plays a "pillar" role in energy security.
Strengthening by science and technology and grasping the initiative
"Chinese can’t develop such a complicated large oil field." At the beginning of the oil battle, some foreign experts asserted. Over the past 60 years, people in Daqing Oilfield have practiced scientific and technological self-reliance and created the world-leading development technology of continental sandstone oilfield with the spirit of "surpassing authority, predecessors and self".

Spontaneous oil production formed by reservoir energy is usually called primary oil production, secondary oil production "squeezes out" oil by water injection, and tertiary oil production "washes out" oil by chemicals. With the continuous development of oil fields, the mining objects have changed greatly.
At the initial stage of development, Daqing Oilfield adopted foreign technology, and the recovery rate was less than 5% at one time. Wang Qimin, an "iron man" in the new era, boldly questioned and put forward the theory of "heterogeneous" development and the method of "efficient water injection", which greatly improved the secondary oil recovery technology and laid the foundation for the oilfield to achieve an annual output of 50 million tons of crude oil. In 2019, Wang Qimin won the honorary title of "People’s Model".
At the end of 1990s, when tertiary oil recovery technology was "stuck", Wu Xiaolin led the team to tackle key problems. After more than 5,600 tests, the monopoly was broken, and the oil recovery of Daqing Oilfield was improved by 14 to 20 percentage points on the basis of secondary oil recovery technology. In 2021, the unconventional oil and gas resources in Daqing Oilfield made another major breakthrough.
Gemee Cheng, an academician of China Academy of Engineering, said that the development history of Daqing Oilfield is a history of self-reliance and scientific and technological progress. Several generations of oil people have continued to struggle, won the national special prize for scientific and technological progress for three times, and accumulated more than 11,000 scientific and technological achievements, building the world’s largest tertiary oil production base.
Nowadays, the more advanced tertiary oil recovery technology has achieved breakthroughs in many aspects such as geological understanding and oil displacement mechanism in Daqing Oilfield.
"Iron Man" never went far.
Behind the breakthroughs again and again is a vivid portrayal of the Daqing spirit (Iron Man Spirit) of "patriotism, entrepreneurship, truth-seeking and dedication". Daqing Spirit (Iron Man Spirit) was first included in the spiritual pedigree of the Communist Party of China (CPC) people.

"When the oil workers roar, the earth will shake three times." The oil workers, represented by Wang Jinxi, fought against each other, and the word "Iron Man" became a loud expression of Chinese’s pride and self-confidence. Liu Li, the winner of "Great Country Craftsman" and an oil production worker in Daqing Oilfield, said that the times are changing and the spiritual belief of Daqing oil people "I offer oil for the motherland" has never changed.
Faced with foreign doubts, Wang Qimin did not believe in evil when he was young, and several people wrote a couplet — — "Don’t look at the young man, dare to laugh at the world’s first-class", and cross-criticize "here is the brave". "There are horses in the rush, and we put ‘ Ma ’ The handwriting was big and broke through ‘ Door ’ Box. " Wang Qimin said, we must blaze a world-class development path.
Li Xinmin, the third generation iron man in Daqing, "drove the well abroad". "Where the well hits, the iron man spirit is brought. Wherever people go, the spirit of Daqing will spread. " Li Xinmin said. The overseas market of anniversary Oilfield has expanded to more than 50 countries and regions.
"Be honest, tell the truth and do honest things", "Strict requirements, strict organization, serious attitude and strict discipline" — — Wang Tianyi, the birthplace of "three old four strictness" and secretary of the Party branch of No.4 Oil Production Team in the third operation area of No.1 Oil Production Plant, said that the "three old four strictness" formed in wartime is still the iron law that Daqing oil people abide by.
"2.5 billion tons is an important coordinate on the road to endeavor in Daqing Oilfield, and it is also a new starting point for a century-old world-class modern oilfield." Zhu Guowen, vice president of China Oil and Gas Co., Ltd. and secretary of the Party Committee of Daqing Oilfield, said. (Reporter Xiong Yanhao, Guan Jiantao, Qiang Yong, Wang He)
