What is the reason for the formation of oil? Causes of the formation of oil

The former is widely accepted, believing that oil is formed by organisms in ancient oceans or lakes after a long period of evolution, which belongs to biological sedimentation to oil and is non-renewable.

The latter believes that oil is generated from the carbon within the earth's crust itself, is biologically independent, and is renewable. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material for many chemical industry products such as solutions, fertilizers, pesticides, and plastics.

Oil, also known as **, is a brownish-black flammable viscous liquid extracted from deep underground. It is mainly a mixture of various alkanes, naphthenes, and aromatic hydrocarbons. It is a mixture formed by the long evolution of organisms in ancient oceans or lakes and is a fossil fuel like coal.

At present, there are two theories about the origin of oil: inorganic theory that oil is formed in mafic magma; Organicism means that all kinds of organic matter such as animals, plants, especially lower animals and plants, such as algae, bacteria, mussel shells, fish, etc., are buried in the bays, lagoons, deltas, lakes and other places that are constantly sinking and hypoxic, and finally gradually form into oil after many physical and chemical reactions.

How is oil formed? How much oil is left on Earth? The truth behind the oil depletion rhetoric.

Principles of oil formation:

It takes at least 2 million years for oil to develop, and the oldest of the reservoirs discovered today is 500 million years old. But some of the oil was generated in the Jurassic.

In the long history of the Earth's continuous evolution, there were some "special" periods, such as the Paleozoic and Mesozoic Eras, when after the death of a large number of plants and animals, the organic matter that makes up their bodies continued to decompose, mixing with sediment or carbonate sediments and other substances to form sedimentary layers.

As the sediments accumulate and thicken, the temperature and pressure rise, and as this process progresses, the sedimentary layers become sedimentary rocks, which in turn form sedimentary basins, which provide the basic geological environment for the formation of oil.

Most geologists believe that oil, like coal and natural gas, was formed gradually by ancient organic matter through a long period of compression and heating. According to this theory, oil was formed by the transformation of prehistoric marine animals and algae carcasses. (Plants on land generally form coal.)

Over a long geological time, these organic matter mixed with silt and was buried under thick sedimentary rocks.

At high temperatures and pressures underground, they are gradually transformed, first forming waxy oil shale and later degenerating into liquid and gaseous hydrocarbons. Because these hydrocarbons are lighter than nearby rocks, they penetrate upwards into nearby rock formations until they penetrate into the tightly impermeable, inherently empty rock formations above. In this way, the oil that comes together forms an oil field.

By drilling and pumping, one can get oil from the oil fields. Geologists refer to the temperature range in which oil forms as the "oil window". If the temperature is too low, oil cannot form, and if the temperature is too high, natural gas will form.

The reasons for the formation of oil are as follows:

1. The first is biochemical oil, which believes that the current oil is mainly dedeposited from biological debris in the ocean or lake in ancient times.

2. The second is petrochemical oil, which is said to be that the Middle East may have gradually turned into land in the early days due to the collision of the earth's tectonic plates. Under certain environmental substances, today's oil was formed.

Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons with a natural occurrence. Petroleum is divided into the forms of **, natural gas, natural gas liquid and natural tar, but it is customary to use "oil" as the definition of "**". Petroleum is a viscous, dark brown liquid known as the "blood of abrasive industry."

There are oil reserves in parts of the upper crust. The main ingredient is a mixture of various alkanes, naphthenes, and aromatic hydrocarbons. It is one of the main objects of geological exploration.

The role of oil

1. Fuel: Petroleum can be distilled from diesel, kerosene and other fuels to provide power for automobile engines and internal combustion engines. The energy emitted by the combustion of oil is enormous, and it can be burned almost completely.

2. Chemical products: Plastics are distilled from Yuanyou key petroleum, and some chemical raw materials such as nylon and polyester used to make clothes are distilled from petroleum and then processed.

3. Paving the road: Oil can be said to make everything you can use. The last oil residue, which became asphalt, paved the asphalt road.

4. Lubricants: Petroleum is also very useful in the field of machinery. Giant gears need oil lubrication to reduce friction, and some small parts also need oil.

The process of formation of oil is:

1.In the ancient oceans, there were many aquatic animals. Some of them are large, some are small, and even have a lot of plankton.

As these creatures die from generation to generation, their remains are deposited on the ocean floor. Some bones have become fossils, but because there is a lot of salt in the ocean, the fat and protein on their bodies cannot be degraded immediately (like pickled salted birds, which can be stored for a long time).

2.Due to the high water pressure on the seabed, the carcasses of animals and microorganisms are gradually compressed over the years. The sedimentary rocks we see thousands of years later are the result of compression. Under intense pressure, fats and proteins gradually liquefy and turn into oil, which is present in sedimentary rocks.

3.A lot of land is also rich in oil, which is due to the movement of the earth's crust.

Petroleum is a viscous, dark brown liquid. There are oil reserves in parts of the upper crust. The main ingredient is a mixture of various alkanes, naphthenes, and aromatic hydrocarbons.

The former is widely accepted, believing that oil is formed by organisms in ancient oceans or lakes after a long period of evolution, which belongs to biological sedimentation to oil and is non-renewable. The latter believes that oil is generated from the carbon within the earth's crust itself, is biologically independent, and is renewable. Petroleum is mainly used as fuel oil and gasoline, and is also a key raw material for many chemical industry products such as solutions, fertilizers, pesticides and plastics. The Chinese name "oil" was first named by Shen Kuo, a great scientist of the Northern Song Dynasty.

Petroleum is a natural organic compound that is mainly composed of carbon, hydrogen, and small amounts of sulfur, oxygen, nitrogen, and other elements. It is a very important energy resource, which is widely used in fuel, chemical industry, medicine, construction and other fields. How is oil formed?

Here are a few common sayings:

1.Organic matter deposition says. This is the mainstream theory of oil formation, and it is also a widely accepted theory.

According to this theory, oil is formed by the deposition of organic matter in the ocean. In the ocean, organic matter such as seaweed, algae, and plankton is deposited over a long period of time and gradually forms a thick layer of organic matter. These layers of organic matter are gradually compressed and metamorphosed through the action of crustal movement, ground temperature, etc., and finally form oil and natural air leakage.

2.Thermal cracking commentary. According to this theory, oil is formed by the thermal cracking of organic matter in underground rocks under conditions of high temperature and pressure.

In the deep part of the earth, crustal movements, geothermal activities and other factors make underground rocks subject to high temperature and pressure, and organic matter gradually decomposes and produces oil and gas.

3.Biomass conversion theory. According to this theory, oil is formed by biomass deep underground through the action of various factors such as microorganisms and chemical reactions.

Deep underground, biomass such as wetland plants, humus, and algae is accumulated and compressed over a long period of time to form biomass coal and microbial hydrocarbons, which are gradually converted into oil and gas over time.

In summary, the formation of oil is an extremely complex process that involves the action of many factors. Different theories give different explanations for different factors, but either theory, they all emphasize the importance of organic matter in the formation of oil. Oil is a very precious natural resource, and we should cherish it and use it wisely.

Oil is an indispensable ecological resource in modern life. Due to the limited reserves of oil resources in the world and the obvious geographical distribution, some countries have a very large amount of oil extraction, such as being called"World oil depots"of the Middle East, the resulting conquest of oil fields is not uncommon. How did such a valuable and important resource come to be?

Not the carcass of an animal. Scientists have the answer.

There are several opinions about the production of oil. Some say that bio-oil is produced. The earliest reservoirs were formed 500 million years ago.

There was a Jurassic period where dinosaurs and plants lived. At that time, the earth was very unstable. After experiencing changes in the ecological environment, the dinosaurs became extinct, and some plants also became extinct.

They are buried together in the ground, and after years of underground chemical reactions, the transformation of these plants and animals continues to ferment with underground carbonates, sediments, and other substances to eventually form a precipitate. This was also the theory that animal carcasses were turned into oil, but this theory was later disproved because the reserves it could produce were far from those found in the world.

The other is the theory of abiotic oil. Oil is stored and exploited in large quantities in the earth's crust. After discovering this phenomenon, scientists began to explore the material beneath the earth's crust.

Oil type is a special substance obtained through a complex chemical reaction process. The earth's crust contains a lot of pickpocketing chemicals. After a series of reactions, the chemical gas encounters magma in the mantle, which, due to its long-term flow in the mantle, cannot oxidize, rapidly deteriorates, and mixes with sediments and underground decaying material to form oil.

Of course, both of these statements have their own convicts, but there are some differences. The oil industry is the blood of economic development, and oil is a non-renewable resource. As a modern, industrialized city and a society where automobiles are commonplace, oil refining has become a multi-fuel vehicle.

The huge amount of energy and heat generated by oil refining is very important. Quality, our world is inseparable from oil, the oil industry is also a country's pillar industry, the world's oil reserves are relatively rich, but this resource will be exploited one day, so now our scientific exploitation, recycling technology is particularly important. Now that we've talked extensively about how oil is produced, and the previous animal carcass theory has been cracked, the most likely theory is the next one.

Is it correct to say that the magma in the spring bond of the earth's mantle undergoes chemical oxidation to form oil? The answer needs to be searched.
