The largest shale oil production base in our country has accumulated production of over 20 million tons.

Today, it was learned from China Petroleum that the country's largest shale oil production base, Changqing Oilfield, has accumulated a production of over 20 million tons of shale oil, marking a new stage of large-scale and efficient development of terrestrial shale oil in China. It took Changqing Oilfield 12 years to reach a cumulative production of 10 million tons from the beginning of shale oil development, and only 3 years to reach 20 million tons from 10 million tons. Currently, Changqing Oilfield's shale oil production accounts for more than half of the total domestic shale oil production, making it the world's first terrestrial shale oil field to achieve large-scale and cost-effective development.
