Chinanews.com, Xi'an, December 27th (Alina Zhang Guoqiang) At 10 o'clock on the 27th, on the electronic display screen of the Changqing Oilfield Production Command Center of PetroChina, the natural gas production curve jumped to 50 billion cubic meters, reaching 50.06 billion cubic meters m, marking the completion of China's first super-large gas production area with an annual output of 50 billion cubic meters.
The oil and gas resources in the Ordos Basin developed by Changqing Oilfield are typical "three low" (low permeability, low pressure, and low abundance) oil and gas fields in the world, and economic and effective development is a worldwide problem.
Changqing Oilfield puts the focus of increasing reserves and production on the basis of basic research and scientific and technological breakthroughs, making breakthroughs in key core technologies for exploration and development of low-permeability, ultra-low-permeability, and tight gas fields, promoting the discovery of oil and gas resources, accelerating the conversion of recoverable reserves, and enabling The "three low" oil and gas reservoirs have exploded with huge energy, thus accumulating and forming the core competitiveness of continuous natural gas production.
According to reports, the average daily gas production of a single well in the Changqing gas area is less than 10,000 cubic meters.
The miracle of high-efficiency development and continuous production increase in such a "barren" gas field is due to the low-cost development model formed by relying on independent innovation to solve the systemic problems of "three low" gas fields.
Changqing Oilfield uses the concept of low cost to systematically plan the high-quality development of tight gas in the basin, focuses on the innovation and optimization of the entire production chain of gas field development and the entire life cycle of gas well management, and promotes the development of horizontal well groups and the commissioning of volume fracturing with high-efficiency development demonstration areas. In the past five years, more than 200 high-yield industrial gas wells of more than one million cubic meters have been obtained.
Overcome the problem of downhole throttling, realize medium and low pressure gas gathering, and make all the ground systems localized.
R & D and application of integrated multi-functional system integration equipment, so that the production process can be arranged according to the best efficiency.
At the same time, Changqing Oilfield continued to promote the digital transformation and intelligent upgrade of natural gas development.
The clean energy processed by the natural gas purification plant is continuously exported to downstream users.

Changqing Oilfield occupies the advantage of being a hub of China's onshore natural gas pipeline network, where the West-East Gas Pipeline and the Shaanxi-Beijing Pipeline converge.
It is reported that Changqing Natural Gas started from the development of Jingbian Gas Field in the 1990s.
With the large-scale development of Yulin Gas Field, Sulige Gas Field, Zizhou Gas Field, and Shenmu Gas Field, the cumulative production of natural gas has exceeded 555 billion cubic meters, which is equivalent to replacing 720 million tons of standard coal and reducing carbon dioxide emissions by 1.956 billion tons. Provide strong support for improving China's energy structure, winning the battle to defend the blue sky, and building a clean, low-carbon, safe and efficient modern energy system.
