The Central Plains base now has Li Siguang, Xie Jiarong, Ding Daoheng and many other outstanding geological experts to carry out theoretical guidance and personal field exploration, and Sun Yueqi, an excellent mining manager, presided over the construction, the superstructure is completely Shijie first-class configuration, coupled with the joint efforts of the vast number of military and civilians in the base area, Hu Weidong also selected some historical sites to find large mines from the exploration jihua book as the focus of exploration, so that the efficiency was further improved. In the past few months, the development of mining in western Henan can be described as changing with each passing day, among which the iron ore because there is no big mine, the speed of construction is particularly fast, the annual output of iron ore broke through the 200,000-ton mark that year, and the following year was more than one million tons in one fell swoop.

Coal mines, on the other hand, are extremely rich in reserves (to what extent?). Since the beginning of the 918 Incident until the end of World War II, Japan has mined more than 200 million tons of coal from Northeast China in more than ten years, and the coal reserves in the Central Plains base area are enough to have tens of billions of tons), Hu Weidong took into account the long-term impact, gave priority to the construction of large and medium-sized coal mines, so the speed is slower than iron ore, but the stamina is undoubtedly stronger, with the current level of development in China, if the coal mines in western Henan can be fully developed, it only takes a fraction of the supply to the whole country.

In addition, copper, lead and zinc and other non-ferrous metal resources have also been developed to varying degrees, only the aluminum smelting industry can not develop, in fact, the Central Plains base area is also quite rich in bauxite resources, and cryolite, an important auxiliary material necessary for aluminum smelting (at this time, the natural resources of the mineral have been basically exhausted, and it has to be synthesized artificially. There are also a lot of fluorite, the most critical raw material for production, but aluminum smelting can only use electrolysis, and the power consumption is very amazing, not to mention the Central Plains base, even if the current national electricity is concentrated. It's just as unbearable. However, the power industry is constrained by the fact that the base areas cannot mass-produce generators, and it is also difficult to achieve rapid development in the short term.

However, the use of aluminum alloys in this era is far from being as widespread as in the future. Especially in wartime, the demand for aluminum in aircraft manufacturing is particularly large, and in special circumstances can also be replaced by other materials such as wood, and even the performance is not necessarily worse than aluminum alloy aircraft, but fuel is indispensable, especially the Red Third Front Army now has some mechanized troops, and the Air Force is not to mention, the aircraft not only has quantitative requirements for fuel, but also has quite high requirements for quality, if you burn ordinary gasoline. Not only will the performance of the aircraft be reduced a lot. And the life of the engine will be greatly shortened, and Hu Weidong does not want to make this decision as a last resort. In addition, a high-powered weapon developed by Hu Weidong in the future also needs oil and gas as raw materials, so the self-sufficiency of oil resources in the Central Plains base area has become very important

The Shaanxi-Gansu-Ningbo Border Region now has China's only oil mine, the Yanchang Oil Mine, and the real reserves of oil and gas in that area are far greater than now predicted. It's just that the two base areas are not directly connected to each other, and it is difficult to transport oil here. And there is an unavoidable problem, Yanchang oil mine is too close to Shanxi, once the Japanese army invades Shanxi in the future, it will become very unsafe, although there is a Yellow River natural danger barrier, it is difficult for the devil's army to fight (in history, the devil's 26th Division and the 109th Division have launched many attacks on the Shaanxi-Gansu-Ningbo border area, but because of the existence of the Yellow River, the devil's forces can not be fully deployed. The maximum offensive force can only have one wing, so it was never able to break through the defense line of the Eighth Route Army, and then the devil gave up. But the devil's planes can bomb the oil mines at any time. Historically, the devil's air raids were mainly aimed at Yan'an, and did not bomb the oil mines, because the output of Yanchang oil mines at that time was very small (only a few tons per day). It's not worth spending a lot of effort to bomb, but now if Hu Weidong wants to pin his hopes on extending the oil field, he must try to increase its production significantly, then the devil will definitely not let it go, which is tangled...,

Hu Weidong was aware of this problem for a long time, and his initial solution was to take advantage of the abundant oil shale resources in western Henan, just by digging up the amount of coal (oil shale is not only a separate deposit, but also a large number of associated coal seams). It's already considerable, but the extraction and refining of shale oil is a shijie problem, mainly because the cost is too high, not to mention that there is no Jishu foundation in the base area, and the cost will only be greater. However, now after taking the Nanyang area, Hu Weidong suddenly has a more haode idea, in history New China found a number of oil fields not far from each other in the Nanyang area, collectively known as Nanyang Oilfield or Henan Oilfield, although the reserves are far from being comparable with the Shijie level oilfield like Daqing, but for this era has been a lot, just one of the Shuanghe oilfields, recoverable reserves of more than 50 million tons

Because Hu Weidong happened to visit the Nanyang Oilfield, the location of several major oil production points is very clear, and there are now many Shijie-level geological experts such as Li Siguang in the Soviet area, so the exploration is very smooth, the first drilling has a valuable industrial oil flow, and the second is a self-injection well that most people are surprised by, and it is expected that the daily output of crude oil will not be less than 50 tons (the peak has reached more than 70 tons, but this is also the largest production, Since then, the maximum daily output of self-blowout wells has been about 10 tons. ), which suddenly exceeded China's total oil production.

Unfortunately, because China was not able to produce its own oil production machinery at this time, Hu Weidong did not prepare in advance, except for a few high-yield self-blowing wells discovered successively, the others could not be used for the time being, and the total daily crude oil output was estimated to be more than 100 tons. However, this is not too big a problem, the oil production equipment is not as focused on by the governments of the world as munitions, and the difficulty of introducing it is not great, as for the difficulty of passing through the national control area, Hu Weidong is not too worried, calculate the time, and wait until the oil production machinery is shipped back, the second KMT-CCP cooperation should have begun, right?

Although those geological experts in the Soviet region have been as cautious as possible in predicting the reserves, the geological reserves of the Nanyang Oilfield must have exceeded 10 million tons just by virtue of those few self-blowout wells, and since many large oil fields have not been discovered in this era, including the Middle East, and the global oil production is less than one-tenth of that of the 21 st century, the oil fields with reserves of more than 10 million tons are considered to be large oil fields. In particular, it will set off a storm in the academic circles, because this area belongs to the continental strata, and the current international geological community generally believes that only in the marine strata can there be large oil fields, only Li Siguang, a geologist who is still unknown in the world, proposed for the first time in 1928 (Note 1) that even if the terrestrial topography is terrained, as long as the number of organic sediments in the geological structure is sufficient and the enrichment conditions are met, it is still possible to form a large oil field, and now the discovery of Nanyang Oilfield undoubtedly provides a strong argument for his thesis.

But Hu Weidong poured a basin of cold water on him, "In order to avoid letting the devil target here too early, the total reserves of this oil field must be kept secret, I hope you can understand, Zhong Gong." ”

Although Li Siguang had some regrets, he did not raise any objections considering the overall situation of the Anti-Japanese War, and he also needed time to sort out the various gains of these days in order to further improve the geomechanical theory, which is still very immature.

Note 1: In 1928, Li Siguang published "The Problem of Fuel" in the Modern Review (1928, Vol. 7, No. 173, pp. 8-12), and from 1935 to 1936, when he was lecturing in England, he wrote a book entitled "Geology of China", which mentioned "sediments of economic value in the East China Sea and North China", which actually referred to oil. Although it has not been elaborated, there is no doubt that Li Siguang was the first to propose that "continental formations may also have large oil fields", and it is by no means Pan Zhongxiang, Huang Jiqing and others who published relevant papers after 1940.

Moreover, Li Siguang's point of view has always been to deny the influence of the classification of marine and continental formations on oil, that is, as long as the sedimentation and reservoir conditions meet the requirements, there may be large oil fields, which has nothing to do with whether the place is a marine formation or a continental formation, and later facts have also proved his thesis, and Pan Zhongxiang, Huang Jiqing and others have put forward the concept of marine and continental facies in their opinions, but they still can't let go of the concept of marine and continental facies, and the two are essentially different (your support is my biggest motivation. )
