The whole of Outer Mongolia was recovered, and Tangnu Wulianghai also controlled a part of it, and in view of the fact that it would not be beneficial for China to continue fighting, Wang Hanzhang decided to go all out to transfer to the construction economy.

If the war continues now, then China must ensure the victory of the war, and naturally there will not be enough energy to develop the economy, if it does not develop industry and develop the economy, even if the Soviet Union surrenders, Wang Hanzhang does not dare to guarantee that Germany will be willing to give Central Asia to China when China is so weak, and how much strength can determine how much share of the profits you have.

At that time, the Song Dynasty was always threatened by the Liao State, and later the Jurchens rose up, and the Jurchens sent people to the Great Song Dynasty to discuss the matter of jointly dealing with the Liao State, and when the Liao State was destroyed, the sixteen states of Yanyun that the Great Song Dynasty dreamed of were returned to the Great Song Dynasty.

The Great Song Dynasty was very satisfied with this, and finally agreed, and later the Liao State was really destroyed, but most of the elite of the Liao State was killed by the Jin Army, and the 600,000 troops of the Great Song Dynasty were defeated by tens of thousands of Liao remnants, which also made the Jurchens see the weakness of the Great Song Dynasty, and their ambitions were further expanded, and finally there was the well-known "Jingkang Shame".

Therefore, although the Germans seem to be very good to China now, they must not have the intention of harming others, but the heart of guarding against others is even more indispensable. Germany now seems to have reached the limit of its military strength and is short of materials, but if the Soviet Union is killed, then the legacy left by the Soviet Union will basically be more expensive than Germany, and when there is no Soviet Union, Germany can go all out to destroy Britain, at least the power of Britain and the United States will feel on the other side of the Atlantic, and after that, whether the Germans will be tempted by the huge Asian territory, Wang Hanzhang has no way to know, Wang Hanzhang only knows that the German ** team can fight better than the Soviet army, so if China wants to be safe, it must have enough strength. If your fists are hard enough, then others won't dare to mess with you easily.

The development of the economy is naturally inseparable from industry, and oil is known as the blood of modern industry, so it is self-evident how important oil is.

China's petroleum resources are concentrated in the eight basins of Bohai Bay, Songliao, Tarim, Ordos, Junggar, Pearl River Estuary, Qaidam and East China Sea Shelf, with recoverable resources of 17.2 billion tons, accounting for 81.13% of the country. Natural gas resources are concentrated in the nine basins of Tarim, Sichuan, Ordos, East China Sea Shelf, Qaidam, Songliao, Yinggehai, Qiongdongnan and Bohai Bay, with recoverable resources of 18.4 trillion cubic meters, accounting for 83.64% of the country.

From the perspective of resource depth distribution, 80% of PetroChina's recoverable resources are concentrated in shallow (< 2000 m) and middle and deep (2000 m~3500 m), while deep (3500m~4500m) and ultra-deep (<4500m) are less distributed. The distribution of natural gas resources in shallow, medium-deep, deep and ultra-deep layers is relatively uniform.

From the perspective of geographical distribution, 76% of China's recoverable petroleum resources are distributed in plains, shallow seas, Gobi and deserts, and 74% of natural gas recoverable resources are distributed in shallow seas, deserts, mountains, plains and Gobi.

In terms of resource grade, high-quality resources account for 63% of PetroChina's recoverable resources, 28% are low-permeability resources, and 9% are heavy oil. Among the recoverable natural gas resources, 76% are high-quality resources and 24% are low-permeability resources.

By the end of 2004, PetroChina had 6.791 billion tons of proven recoverable reserves, nearly 14.4 billion tons of unproven recoverable resources, and 32.03% of recoverable oil resources. The proven recoverable reserves of natural gas are 2.76 trillion cubic meters, the recoverable resources to be proved are 19.24 trillion cubic meters, and the proven degree of natural gas recoverable resources is only 12.55%, which is in the early stage of exploration, and the discovery of reserves in the near and medium term is expected to grow rapidly.

Since the early 50s of the last century, China has carried out oil and gas exploration in 82 major large and medium-sized sedimentary basins, and discovered more than 500 oil fields. The following are China's major onshore oil producers.
