On the 2nd, the Information Office of Gansu provincial government held a press conference to disclose that by the end of 2021, Petrochina Company Limited(601857) Changqing Oilfield had an annual oil and gas equivalent of 10.09 million tons in Gansu Development Area, marking the full completion of a 10 million ton oil and gas production base in Qingyang old revolutionary base area, which is of great significance to ensuring national energy security, optimizing regional energy structure It is of great significance to promote the rapid development of local economy.
Qingyang has 7.88 billion tons of oil reserves, accounting for 41% of Inner Mongolia Eerduosi Resources Co.Ltd(600295) basin, and 3.21 billion tons of proved geological reserves; The predicted coal reserves are 236 billion tons, accounting for 97% of the reserves in Gansu Province, and the proved geological reserves are 21.5 billion tons; The reserve of natural gas resources is 2 trillion cubic meters, the exploitable amount of wind energy resources is about 8 million KW, and Cecep Solar Energy Co.Ltd(000591) resources can meet the demand for photovoltaic power generation of more than 1.5 million KW. The area is rich in energy resources, and oil, gas and scenery resources coexist.
The annual oil and gas equivalent of Changqing Oilfield accounts for one sixth of the country. Qingyang is the birthplace and main production area of Changqing Oilfield. At present, the Qingyang development area covers 8 counties and 106 townships, forming 4 major oil producing counties of one million tons.
Petrochina Company Limited(601857) Changqing Oilfield Company Executive Director and party secretary he Jiangchuan said that in the 1970s, Changqing Petroleum launched the Shaanxi Gansu Ningxia oil conference in Qingyang, which lasted 23 years and built a million ton oil field to support the economic construction of the motherland. In the late 1990s, the main forces of exploration and development moved east to northern Shaanxi and north to Inner Mongolia, shifting to the strategy of “simultaneous development of oil and gas”, opening a new journey of building China’s large oil fields.
“The oil and gas resources in Longdong area are typical ‘three low’ (low permeability, low pressure and low abundance) oil and gas reservoirs in the world. The reservoir is as dense and hard as a grindstone.” Petrochina Company Limited(601857) Shi Daohan, deputy secretary of the Party committee and general manager of Changqing Oilfield Company, said that in order to break the worldwide problem of economic and effective development, Changqing Petroleum people have adhered to basic research and technological breakthrough for decades, committed to building a “diamond” for finding oil and gas resources, cracked the “trump card” for “three low” oil and gas development, and formed an original geological theory for rapid access to oil and gas resources, Master the key core technologies such as three-dimensional seismic, optimal and fast drilling of horizontal wells and volume fracturing in the Loess Plateau.
Since 2018, Changqing Oilfield has applied three-dimensional seismic and high-precision logging technology to prove China’s first Qingcheng oilfield with shale oil reserves exceeding 1 billion tons in three years, innovatively integrated 18 supporting technologies in five series of shale oil development, and explored and formed a three-dimensional development of horizontal wells and industrialized operation mode of large well clusters, China’s first shale oil development demonstration zone with an annual output of one million tons was built in Qingyang, creating a precedent for the economies of scale development of continental shale oil in the world. Up to now, Longdong Oil area has produced 110 million tons of oil and gas equivalent.
At the same time, Changqing Oilfield takes Longdong Oil and gas development as a model for practicing the new development concept, promotes the revolutionary measure of “resource conservation, environment-friendly, co construction and sharing”, and explores the formation of five ecological protection modes such as Nanliang forest edge area and Huachi water edge area; The comprehensive utilization rate of oil well associated gas was increased to 91%, water resources were recycled to 100%, and 1600 mu of land was saved for the construction of one million tons of oil production capacity; More than 500 oil wells in nature reserves and water sources have been blocked, the construction of carbon sequestration forests in many regions has been started, more than 5000 clean and civilized well pads have been built, and Xifeng Oilfield and Nanliang oilfield have entered the list of national green mines, contributing to the construction of ecological security barrier on the Loess Plateau.
In December 2021, Qingyang held the fifth Party Congress, which determined to implement the “two wheel” driving strategy of accelerating the construction of Longdong comprehensive energy and chemical industry base and regional central city.
At the press conference on the same day, Zhou Jijun, deputy secretary of Qingyang municipal Party committee and mayor, said that the completion of a 10 million ton oil and gas production base in Qingyang old revolutionary base marked a new era in the development of Qingyang’s oil and gas resources, and the construction of Longdong national modern comprehensive energy base reached a new level, which is of milestone significance to national energy security and Qingyang’s high-quality development. Looking forward to the journey of striving, we will work together to draw a new blueprint of high-quality co construction of “mechanism integration, industry integration and service integration” between local enterprises.
During the 14th Five Year Plan period, Changqing Oilfield initially plans to invest 80 billion yuan in Longdong area. It is expected that by 2025, the annual oil and gas equivalent in Longdong is expected to reach more than 12 million tons, which will play a greater role in supporting the economic and social development of the old revolutionary base areas and ensuring the extension of the oil and gas industry chain.
