Bio-Oil Theory (Lomonosov Hypothesis)
Studies have shown that the generation of oil takes at least 2 million years, and among the oil reservoirs discovered today, the oldest is 500 million years old. But some oil was produced in the Jurassic. In the long history of the earth’s continuous evolution, there are some “special” periods, such as the Paleozoic and Mesozoic, when a large number of plants and animals died, and the organic matter that made up their bodies continued to decompose and mix with materials such as sediment or carbonated sediments composed of sedimentary layers. Due to the continuous accumulation and thickening of sediments, the temperature and pressure rise. As this process continues, the sedimentary layer becomes sedimentary rock, and then sedimentary basins are formed, which provides the basic geological environment for the generation of petroleum. Most geologists believe that oil, like coal and natural gas, was gradually formed by the long compression and heating of ancient organic matter. According to this theory, oil was formed by the transformation of prehistoric marine animals and algae corpses (land plants generally form coal). The organic matter was mixed with silt over long geological ages and buried under thick sedimentary rocks. Under high temperatures and pressures underground they are gradually transformed, first forming waxy oil shale and later degrading into liquid and gaseous hydrocarbons. Since these hydrocarbons are lighter than the nearby rock, they permeate upward into nearby rock formations until they penetrate the tight, impermeable, and inherently porous formation above. The oil thus gathered together forms an oil field. Oil is obtained from oil fields by drilling and pumping. Geologists refer to the temperature range in which oil forms as the “oil window.” The temperature is too low to form oil, and the temperature is too high to form natural gas.
