Petroleum is one of the most widely used natural resources. As the most important resource on earth, there are two theories about the formation of petroleum. oil theory.
Cause ​1: Ancient creatures formed after a long period of deposition
This cause, also known as the “biological oil theory”, believes that the oil on the earth is formed by ancient organisms buried in the soil after long-term compression and heating. Scientists have also found the origin of coal and natural gas through the origin of oil. Scientists believe that the bodies of ancient marine animals and algae formed oil, coal evolved from vegetation on land, and natural gas was formed by high-temperature steam after the organisms formed oil, so the oil on earth was formed by ancient organisms. of.
Cause 2: The theory of abiotic oil formation
However, some scientists disagree with the bio-oil theory because they think it is impossible to create such a rich oil reserve by wasting the bodies of ancient organisms. If we want to form so many oil reserves today, we must have several times the number of living things. Therefore, some scientists have come up with another theory: the abiotic oil theory, the abiotic oil theory, as the name suggests, is that oil is produced through rock formations. Scientists have found that the Earth’s crust is rich in carbon, which naturally forms hydrocarbons, and they also found very strong evidence. For example, scientists have found that after some dry wells are abandoned, they can still produce oil after waiting for a long time. This shows that oil cannot evolve from biological corpses, because it takes hundreds of millions of years. Therefore, the formation of oil is caused by Produced by the radioactive action of hydrocarbons in the Earth’s interior.
at last
No matter what form of oil is formed, its formation process is not simple. After all, humans cannot produce oil. With the development of modern society, the demand for oil has greatly increased. Some people worry that oil resources will soon be depleted. In fact, this concern is superfluous, since the Earth’s oil reserves are much more abundant than expected. Since the earth is so rich in oil, why is the earth’s oil resources always used up within 50-100 years? In fact, it’s an “oil scam”. The so-called 50-100-year depletion of oil means that some of the profitable oil reserves can be exploited within 50-100 years, while some of the unprofitable oil reserves can support human beings for a long time. Some scientists even assert that even if humans die, the oil on Earth will not be depleted because oil is abundant and renewable, it just takes longer to regenerate.
Although the oil resources on the earth cannot be exhausted in theory, due to the serious environmental pollution caused by the use of oil, it is imperative to develop new energy sources to replace oil. Only when the environment is improved can human beings develop sustainably.
