[Explanation] On March 2, the Gansu Provincial Government Information Office held a press conference to disclose that by the end of 2021, PetroChina Changqing Oilfield's annual oil and gas equivalent production in the Gansu development area reached 10.09 million tons, marking 10 million tons in the old revolutionary base area of Qingyang. The comprehensive completion of oil and gas production bases is of great significance for ensuring national energy security, optimizing regional energy structure, and promoting rapid local economic development.
Shi Daohan, deputy secretary of the party committee and general manager of PetroChina Changqing Oilfield Company, said at the press conference that in order to break the worldwide problem of economical and effective development, Changqing Petroleum people have adhered to basic research and technological breakthroughs for decades, and are committed to building a search for oil and gas resources. The "diamond drill" of the company, the "one-stop solution" for cracking the "three-low" oil and gas development, formed an original geological theory for rapid acquisition of oil and gas resources, and mastered key core technologies.

We adhere to openness and sharing, gather intelligence to tackle key problems, and work with engineering and technical service units and scientific research institutes to tackle key problems to create "four major technologies".
The 3D seismic technology of the Loess Plateau has broken through the many barriers of the thick loess layer in Longyuan, and the reservoir identification accuracy has been improved by more than 30%, effectively supporting major exploration discoveries.
The excellent and fast drilling technology for horizontal wells has boosted the speed and efficiency of engineering construction, creating a number of construction records such as the shortest drilling cycle and the longest horizontal well in China.
The volume fracturing technology has opened up oil and gas "seepage channels" in tight rocks, and the single well production has been increased by more than 2 times. The comprehensive stable production plan has extended the development life of oil and gas reservoirs.
[Commentary] He Jiangchuan, Executive Director and Secretary of the Party Committee of PetroChina Changqing Oilfield Company, reviewed the historical introduction at the press conference. In the 1970s, Changqing Petroleum people launched the Shaanxi-Gansu-Ningxia Petroleum Battle in Qingyang, which lasted for decades Always insist on making contributions to the economic construction of the motherland.

We have finally realized the construction of a ten-million-ton oil and gas production base in the old district of Qingyang. I feel that its significance is to be more confident in ensuring national energy security.
We all know that our oil and gas industry is highly dependent on foreign countries. Therefore, the seven-year development plan for oil and gas business formulated by the state requires us to reduce the dependence of the oil and gas industry on foreign countries. Changqing Oilfield is the largest oilfield in China. It can be said that the entire Changqing Oilfield Oilfields, including the Qingyang area, have to shoulder the major political responsibility of ensuring national energy security.
[Explanation] It is understood that Qingyang has oil reserves of 7.88 billion tons, coal reserves of 236 billion tons, natural gas reserves of 2 trillion cubic meters, wind energy resources of about 8 million kilowatts, and solar energy resources of more than 1.5 million kilowatts. demand for photovoltaic power generation.
The area is rich in energy resources, and the oil, gas, light and wind resources coexist.
Since 2018, Changqing Oilfield has applied 3D seismic and high-precision logging technology, and in three years, it has proven my country's first shale oil reserves of over 1 billion tons in Qingcheng Oilfield, and has innovatively integrated five series of shale oil development. 18 supporting technologies have been explored to form the three-dimensional development of horizontal wells and the industrialized operation mode of large well clusters, creating a precedent for the large-scale and profitable development of continental shale oil in the world.
Up to now, the Longdong oil area has produced 110 million tons of oil and gas equivalent.
