The oilfield became China's first mega oil and gas field that reached the 60-million-ton annual production level.

The annual output of Changqing Oilfield accounted for nearly one-sixth of the country's domestic production.

Based in Northwest China's Ordos Basin, the fast-growing oilfield has so far produced the equivalent of more than 760 million tons of oil in crude oil and natural gas cumulatively.

The Changqing Oilfield stretches over Shaanxi, Gansu and Shanxi provinces as well as the Ningxia Hui Autonomous Region and Inner Mongolia Autonomous Region.

As China's biggest natural gas production site, the vast oilfield secures over 44.5 billion cubic meters of natural gas per year to more than 50 large- and medium-sized Chinese cities including Beijing, playing an important role in safeguarding the regional energy security.

The oilfield has produced 463.8 cubic meters of natural gas since the start of production in 1997, helping reduce carbon emissions by around 380 million tons.

The oilfield is expected to see annual production grow to the equivalent of 68 million tons of oil in crude oil and natural gas during the 14th Five-Year Plan period (2021 to 2025).
