In the hinterland of the Maowusu Desert in April 2026, the silver device of the second purification plant of Changqing Oilfield shines coldly in the sunlight. On the large screen in the central control room, the operational data of over 20000 gas wells is updated with a second level frequency jumping. Just a few days ago, China's largest natural gas production base just handed over its first quarter report card -13.727 billion cubic meters. Behind the numbers is an energy relay from the depths of the desert to the stoves of thousands of households.

Intelligent gas well coverage exceeds 80%

More than 85% of the gas reservoirs in Changqing Oilfield belong to low-permeability, low-pressure, and low abundance tight gas reservoirs, with a single well gas production of less than 10000 cubic meters. In the first quarter, the oilfield implemented potential tapping and transformation on more than 14000 old wells, innovatively applied three key technologies, and increased the average daily gas production per well by 15%. At present, the coverage rate of intelligent gas wells has reached 85.66%, and the digital command center provides 24-hour precise scheduling. Gas well management has moved from empirical judgment to the era of data decision-making.

Four gas storage facilities for peak shaving and supply guarantee

After the heating season ended, the four gas storage facilities in Changqing Oilfield quickly switched to gas injection mode, injecting a total of 2.3 billion cubic meters of gas to prepare sufficient inventory for the next round of supply guarantee. During the heating period, the gas storage tank adopts a refined scheduling approach of initial production control and stable storage, and full peak shaving during peak hours. The maximum daily gas production reaches 18.52 million cubic meters, and the peak shaving capacity has increased by 40% compared to the previous heating season. The Jingbian gas field is simultaneously promoting green technologies such as single station boosting and solar energy with battery heating, aiming to reduce consumption and increase production in both directions.

Green power and CCUS are simultaneously increasing their investment

In the first quarter, the clean power generation of oil fields reached 153 million kilowatt hours, a year-on-year increase of 18.6%. The construction of the first centralized external photovoltaic project in Yanchi, Ningxia is accelerating, with 178000 photovoltaic panels laid out in a contiguous manner. The large-scale application of CCUS technology continues to deepen, with the coordinated promotion of carbon dioxide oil displacement and storage, and the steady increase in associated gas recovery and utilization rate. From fine tapping of tight gas reservoirs to multi energy complementarity of wind, solar and energy storage, Changqing Oilfield is laying out a supply network interwoven with traditional and new energy in the Ordos Basin.Editor/Gao Xue
