Focusing on high -quality development 丨 more than 2.4 billion tons! - "Number" says that my country's largest oilfield "three changes" ending energy rice bowl

Xinhuanet, Harbin, September 26th. On September 26, 1959, Daqing Oilfield was discovered. Over the past 63 years, the largest oil field in my country has produced more than 2.4 billion tons of crude oil, accounting for about 40%of the total number of crude oil in the same period of the country, providing a surging and long -lasting kinetic energy for the Chinese economic giant wheel.

The Daqing Oilfield, which shoulders the major responsibility of "Being a good benchmark flag and building a century -old oil field", vigorously promotes the spirit of Daqing and the spirit of the iron man, and continues to move towards high -quality development in the transformation of "technology oil fields", "green oil fields" and "digital oil fields". Contribute to the national energy rice bowl.

Drilling about 360 Mount Everest: Forever "spirit" vitality cast petroleum industry monument

As of the end of 2021, the 1205 drilling team of the Daqing Oilfield has accumulated a total of 2491 wells, with a total of 3.183 million meters, which is equivalent to drilling about 360 Mount Everest.

Behind the numbers is a vivid footnote for Daqing Oilfield to promote the spirit of Daqing and the spirit of the iron man.

1205 Drilling Team -The "Iron Man" Wang Jinxi has brought the team on the way to find oil for the country.

On a towering manhole, the "Iron Man team forever" is particularly noticeable. Under the manhole, Zhang Jing, the captain of the 1205 drilling team, and the team members lived a dragon. They were patient and tested, and put a blood in the hard work.

More than 1205 drilling teams. Over the past 63 years, the generation of workers of Daqing Oilfield has continuously enriched, perfected, and summarized the profound connotation of Daqing's spirit and iron man spirit in the practice of "I donate oil for the motherland". The spirit of Daqing and Iron Man, which formed the age of the Petroleum Conference, is radiating the glorious glory of the era.

"Iron Man" never go far, similar examples abound.

In September of this year, the Oil Six Factory La-II Joint Station's sewage trunk line was perforated, and the scene was complicated. The trunk line was directly below the multiple pipelines and cables.

"We can do it with the machine, and we can do it if the machine can't do it!" The employees at the scene were not shrinking. They stood in the mud water and dug hands. They dug more than 1 meter deep in just one hour. In the case of non -stop production, the repair was completed in two hours.

"Stabilizing oil" also needs to "increase gas". Daqing Oilfield accelerates the leap from "one oil" to "oil and gas", making "energy granary" more solid.

In March of this year, the national key project, the four -station gas storage group, officially opened gas injection, with an average daily gas injection of 1.5647 million cubic meters.

"We maximize the ability to reserve the supply of gas storage to increase the supply capacity, and the fourth storage gas storage group can achieve early gas injection." Said Wang Changhao, deputy chief of the gas -storage database development management section of Daqing Oilfield Development Division.

Over the past 63 years, Daqing Oilfield has created a miracle in the history of the development of the world oil field. After achieving high yield and stable production of crude oil for more than 50 million tons for 27 consecutive years, the annual output of oil and gas has always maintained more than 40 million tons. As of 2021, a total of 2.463 billion tons of crude oil and 146.23 billion cubic meters of natural gas were produced.

After dozens of years of wind and rain, Daqing Oilfield has cast an immortal monument for the Republic's industry.

Increase the harvest rate by 20 percent

In the Daqing Oilfield, the harvest rate is equivalent to finding a large oil field for every one percentage point. The Daqing Oilfield broke foreign monopoly and achieved a major breakthrough in three oil collection techniques. It can increase the harvesting rate of 20 percentage points on the basis of traditional water drive technology.

"Beyond the authority, beyond the predecessors, and beyond yourself" -The history of development and construction of Daqing Oilfield is a history of scientific and technological progress and a history of continuous innovation. Several generations of petroleum people have established a technological foundation for ensuring national energy security with continuous innovation results.

In the oil industry, the first oil collection refers to the oil by the natural energy of the strata. The secondary oil mining "squeeze" the oil through water injection, and the oil collection is "washed" by the chemical agent.

Wang Qimin, the second generation of "Iron Man" in Daqing Oilfield, boldly questioned the "mild water injection" and "balanced mining" theory of foreign experts, and proposed the theory of "non -homogeneous" development and "high -efficiency water injection mining". The continuous improvement of the second oil collection technology has laid the foundation for the realization of the annual output of 50 million tons of high yield and stable production.

With the difficulty of the development of oil resources, in the face of the reality of "stuck neck" in the face of three oil recovery technology, Wu Xiaolin, chief technical expert of Daqing Oilfield, led the team to carry out hard work. After more than 5,600 trials, domestic surface activity was developed. The agent has achieved three major breakthroughs in oil collection technology.

As of the end of 2021, the three -time oil field recovery of Daqing Oilfield produced more than 10 million tons of oil for 20 consecutive years, and the cumulative production of crude oil was 286 million tons of three times, and the world's largest three oil recovery bases were built.

The footsteps of scientific and technological innovation have never stopped.

After three oil collection, the water content of the oil layer has been close to 98%, which is equivalent to "looking for oil and water in water in water". The four oil collection techniques currently explored by Daqing Oilfield are a more intelligent, efficient and accurate improvement of harvesting technology. , Can fully excavate the potential of oil collection.

"Daqing Oilfield's four -time oil recovery technology has achieved breakthroughs in many aspects such as geological understanding and oil -driven mechanism, which provides useful exploration for further improving the harvest of the old oil field." Said Cheng Jiecheng, an academician of the Chinese Academy of Engineering.

Since the discovery of Daqing Oilfield in September 1959, generations of Daqing Petroleum People have always been committed to independent innovation of science and technology, and they have been diligent in creating the "Kingdom of Petroleum Technology". The remaining item. At present, the "63 -year -old" Daqing Oilfield still maintains high -level scores of an annual output of oil and gas of more than 40 million tons.

About 600 million tons of oil -containing sewage "zero emissions" every year: decreased carbon reduction to "green future"

Each year, the oilfields need to be treated with about 600 million tons of oil. If it is directly discharged, it will cause severe environmental pollution. The oil field continues to build oil sewage treatment stations and sewage pipe networks, and the oil -containing sewage that has been dealt with is returned to the oil layer.

The oil -containing sewage realizes "zero emissions", and the return oil layer also solves the problem of weakening the supporting force of the formation after crude oil mining.

In September of Golden Autumn, in the cover of urban wetland reeds, tens of thousands of "hoe machines" were scattered in all corners of Daqing, and they "swayed" rhythmicly. Overlooking, surrounded by blue sky, white clouds, and water systems, several generations of petroleum people also protect the ecological environment here while building a petroleum city, and build a solid foundation for the sustainable development of cities and oilfields.

In Daqing Oilfield, carbon dioxide drivers and other technologies have also matured. The carbon dioxide over one million tons of carbon dioxide has been injected underground, reducing carbon emissions, and reunification of production benefits and ecological benefits.

In the elm forest oil field affiliated to Daqing Oilfield, the staff is monitoring carbon dioxide -driven equipment in the central control room. In the courtyard, several large carbon dioxide storage tanks stand on the bracket. These carbon dioxide are originally the gas of the factory, which can now be used to help picking oil and reducing pollution.

"Many carbon dioxide generated by the factory is an exhaust gas to others, and in our opinion, it is a 'baby'." Pang Zhiqing, manager of the new energy project manager of Daqing Oilfield.

Daqing Oilfield focuses on the construction of "green and low -carbon sustainable development demonstration bases", and is vigorously promoting the development of wind, light, gas, and electrical integration, and develop new energy technologies such as industrial heat and geothermal use. It is planned that by 2025, the scale of new energy installation will reach 2 million kilowatts, and the clean energy replacement rate will be more than 20%.

"Green" to win the future, "Zhi" oilfields.

At the production management center of the eighth operation area of ​​the third oil plant in Daqing Oilfield, the operator found the data of a well 10 kilometers away through the real -time data passed back to the oil well, and immediately issued a well washing instruction.

"In the past, we washing wells, how long washing, and to what extent, these were judged through experience. Now through parameters, we know when to wash and well, and the work efficiency is improved." Say.

The global energy industry is facing a comprehensive and subversive change. In recent years, Daqing Oilfield has vigorously promoted the three -step strategy of "digital oil fields, smart oil fields, and smart oil fields". At present, digital oil fields have begun to take shape.

"Today's Daqing Oilfield has entered a new stage of high -quality development and is working hard to build a century -old oil field." Zhu Guowen, vice president of PetroChina Natural Gas Co., Ltd. and secretary of the Party Committee of Daqing Oilfield. (Finish)
