In the past decade, China has newly discovered 23 large oilfields of 100 million tons and 28 large atmospheric fields of 100 billion square meters

Yu Haifeng, director of the Department of Geological Exploration and Management of the Ministry of Natural Resources, said at a series of theme press conferences of the Propaganda Department of the CPC Central Committee on September 19 that in the past ten years, China's petroleum and natural gas have newly discovered 23 large oilfields of 100 million tons and 28 large air fields of 100 billion square meters, and 32 new resource bases
have been formed for non-oil and gas minerals.

Yu Haifeng said that since 2011, China has organized and implemented strategic actions
to break through prospecting.
In the past ten years, a number of strategic succession zones for important mineral resources have been formed, and the amount of major mineral resources has generally increased under the condition that mining consumption has continued to increase
.

From a regional point of view, the newly proved geological reserves of oil in the west account for more than half of the whole country, and the output accounts for about one-third
of the country.
The newly proven geological reserves and production of natural gas in western China account for more than
80% of the country.
Marine oil and gas production accounts for about a quarter of the country's total
.
In particular, in 2021, the crude oil production of Bohai Sea Oilfield will exceed 30 million tons, and the new output will increase
significantly.
In addition, 32 new non-oil and gas mineral resource bases have been formed, 25 of which are in western
China.

According to Yu Haifeng, in the past ten years, more than 80 old mines have reached a large and medium-sized scale, and nearly 800 production mines have extended their service life
to varying degrees.

In addition, the degree of basic geological survey work has been continuously improved, the coverage rate of 1:50,000 regional geological surveys has increased from 24.
7% to 45.
5%, and the survey of important prospecting prospecting areas has been fully covered
.
At the same time, scientific research achievements such as "geological theoretical innovation and major breakthrough in mineral prospecting on the Qinghai-Tibet Plateau" and "trinity" prospecting prediction theory in the solid mineral exploration area have greatly supported domestic prospecting actions
.

In the past decade, China has also issued the "three rates" (mining recovery rate, mineral processing recovery rate, comprehensive utilization rate) index requirements for 124 mineral species such as coal and iron, and selected and promoted 360 advanced and applicable technologies, processes and equipment, with an average increase of 9 percentage points in oil recovery, an average increase of 8 percentage points in the recovery rate of solid mineral extraction, and an average increase of 9.
5 percentage points in
the recovery rate of mineral processing.

At the same time, we will promote the revision of the Mineral Resources Law of the People's Republic of China, deepen the reform of the mining rights transfer system, and form a new specification for the classification of China's mineral resource reserves
.

In the next step, Yu Haifeng said that the Ministry of Natural Resources will also work with relevant departments to organize a new round of strategic actions
for prospecting breakthroughs.
