How is oil formed underground?

Our textbooks tell us that oil was formed from the remains of ancient creatures through a long geological period. But now many scientists have questioned this.

Of course, this suspicion is reasonable, but the theory of organic origin of oil cannot be completely ruled out. Perhaps, the origin of oil is more complicated than we know, and we don't fully understand it.

The basic substance that forms oil is methane. Recognizing this, many problems can be explained. But there are still many people who think that natural gas is a by-product of oil, and oil is derived from natural gas instead of natural gas to form oil. The main component of natural gas is methane. In other words, we haven't reached an agreement on who will form oil and natural gas. We know that methane is easy to form. Methane can be produced by organic matter decomposition or geological activities such as volcanoes. Therefore, it is possible to form oil through inorganic processes.

Therefore, the source of oil is not single, and the oil that may be formed through geological activities accounts for a larger proportion. But in any case, the formation of oil is related to the ocean. It is formed in the marine environment.

The formation process of petroleum can be described as follows:

(1) Methane forms combustible ice under the action of ocean pressure. The source of marine methane may be the result of organic matter decomposition or volcanic activity.

(2) The deeper the combustible ice is buried in the seabed sediments.

(3) Due to the crustal pressure, combustible ice changes in blood circulation and becomes a polymer of macromolecular organic compounds, namely petroleum. In this process, there is always some combustible ice that has not turned into oil. With geological activities, the pressure decreases and becomes natural gas again.

(4) Due to geological activities, although oil migrated along the fault, it was enriched together to form an oil-rich area. This is an oil field.

I always feel that oil and coal existed when the earth was formed. They were originally a part of the earth, not animal carcasses or trees. As far as the huge storage of oil is concerned, how many animal carcasses can be formed, and the animal carcasses will be eaten and decomposed by bacteria in a very short time, so it is impossible to form oil, so it is impossible to form corpses.

What about the carbonized wood that scientists found in the coal seam? I think coal and oil are the same thing, but because of the crustal movement, a large amount of oil gushed out of the surface, and trees inevitably occupied oil. After several years, volatile oil substances evaporated through repeated or repeated crustal movements and were buried underground, and oil and trees became coal together.

Why do I say that oil and coal (plus a natural asphalt) are the same thing? Coal is much closer to the surface, oily substances volatilize, and the non-volatile parts are preserved and solidified. Oil is buried deeply, and oily substances are not volatile, so it can always remain liquid.

Personal opinion, please don't joke.

Oil is made from animal carcasses and coal is made from trees! The world has long been conclusive. In coal mines, we often see undecomposed branches. This is not controversial in the scientific community, and civil disputes are only civil issues.

There are two issues to be clarified. What is plastic made of? Oil. What is the fertilizer produced? Oil. They are all made of nontoxic petroleum. Only in the production process, chemical raw materials are decomposed, so they are chemicals.

At the end of Cretaceous, the asteroid ring hit the earth, which led to the activation of the platform. The metal hydrogen ions produced by the material flowing at the speed of light in the crater magma shock wave laminar flow polymerized to form hydrocarbons, which degraded the paleontological corpse to form oil. Oil is generally buried in underground depressions, but it will also be exposed to the surface and volatilize to form "asphalt lake".

This question is very interesting. I'm afraid there is no very objective, correct and convincing answer in this world so far. All the "conclusions" are just guesses. For example, a person is born with internal organs, seven limbs, blood, food and oxygen. Who knows why Taoist priests grow like this? Perhaps the earth, like human beings, is an object with life and soul, and it must have the same material structure as human beings, such as blood circulation, physiological characteristics and living environment. Maybe one day, when human science and technology are so advanced that even a speck of dust can't escape people's sight, that is the best time to solve the earth's problems!

Oil is the corpse of living things, and the cells of living things contain fat and grease, which are composed of three elements: carbon, hydrogen and oxygen. When biological debris settles on the seabed or lake bottom and is covered with mud, oxygen is separated and carbon and hydrogen form hydrocarbons.

There is no conclusion! Inorganic genesis, organic genesis, non-organic genesis and so on. I prefer the inorganic origin theory.

It is the deeper carbon ions and hydrogen ions that move up and polymerize along the formation fractures, and Tomo reaction occurs to form hydrocarbons, which are polymerized and migrated many times to form oil reservoirs in the reservoirs.

Textbooks talk about the formation of animal carcasses, which I think is natural! Controversial!
