Is oil depletion a hoax? How is oil formed, and why are global reserves increasing?
That is, China has discovered new oil fields one after another in Daqing and the Tarim Basin in Xinjiang, and these two large oil fields have been explored for more than 1 billion tons of oil, which once again broke the theory that oil is about to be exhausted. In fact, there has always been the question of how many years the oil can be used, but the oil has never really been depleted. On the contrary, the global oil reserves have been increasing. What is going on?
Oil is the first energy element in the world's industry today, and it is also known as the blood of contemporary industry. If a country wants to survive and develop, it cannot do without oil, an important strategic resource. Since the discovery of oil by humans, the application of oil has never been interrupted, ranging from tanks, rockets and other spacecraft to small food, clothing, housing and transportation, and it permeates all aspects of human life.
But how is oil formed? It has always been a mystery, but it can generally be divided into "organic causes" and "inorganic causes". The former believes that oil is a non-renewable resource, and believes that oil is formed by microorganisms after a long evolution. After the organisms die, part of their corpses will be destroyed by oxidation and decomposition, and formed over time under certain temperature and pressure conditions. "Raw Oil". After many times of migration, oil reservoirs are formed, which are then discovered, exploited and utilized by us; while the latter believe that oil is a renewable resource, which can be continuously formed in the earth's crust, and they believe that oil is composed of carbon elements in the earth's crust itself. After a variety of physical and chemical reactions generated. Although there are different opinions on the formation of oil, the exploration of oil has never stopped, especially the research on how to extract oil reasonably and effectively.
In the early days of oilfield exploitation, people at that time did not have advanced technology, so they could only drill down through a well in the oilfield on the surface, and then the oil would spew out directly, but in this way, the oil recovery rate was only 5% Therefore, people's pursuit of oil extraction technology, related applied science and engineering technology system has always been the goal. For example, the tertiary oil recovery technology adopted in Daqing, China, the application of this technology is based on the perfect integration of biological, physical and chemical technologies, which greatly improves the oil recovery rate of oil fields.
The primary oil recovery technology is the most convenient oil recovery stage, mainly to extract the oil on the surface of the formation to realize the self-injection oil recovery technology; the secondary oil recovery technology is to inject water into the bottom layer to increase the pressure of the formation, and convert the pressure into energy. The tertiary recovery is mainly to wash out the oil, because in the process of the secondary oil recovery, there will be oil still hidden in the pores of the rock formation. At present, the recovery rate of this technology can reach 30%, but there are also many problems in the process of tertiary oil pumping. The output of Daqing alone in 16 years is also tens of millions of tons.
Oil extraction technology is still improving, but the amount of oil is increasing day by day. People can't help but worry, will the oil run out one day? Scientists once predicted that when oil production reaches a peak, it will decline, but is this true? Actually not. In fact, the amount of oil storage has been rising all the time, mainly due to the upgrading of technology, which allows people to drill deeper into the ground for oil, and the oil resources that can be detected at present are expected to be used for decades. This is what people can detect, and there are actually more oil resources that people have not detected.
Therefore, the storage capacity of oil is no longer a concern of people, but how to find clean resources to replace it. Because the burning of oil will release greenhouse gases, and these gases will destroy the earth's atmosphere. Repeatedly, the world has fallen into a vicious circle, which is detrimental to the survival of human beings in the long run. Therefore, the development of clean energy is imminent.
