Background

Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid, called "industrial blood", with petroleum reserves in the upper part of the crust. The main component is a mixture of various alkanes, cycloalkanes and aromatics. The oil formation mechanism of petroleum has two theories of biological deposition and oil change and petrochemical oil, the former is widely accepted, and the petroleum is formed by the long evolution of organisms in ancient oceans or lakes, belongs to biological deposition and oil change and cannot be regenerated; the latter considers that oil is produced from the carbon in the earth's crust itself, is biologically unrelated and is renewable. Petroleum is mainly used as a fuel and gasoline, and is also a raw material for many chemical industry products such as solutions, fertilizers, pesticides, plastics, and the like, and petroleum is a fluid mineral buried deeply in the ground. In 1982, the world oil production was 26.44 billion tons and the natural gas was 15829 billion cubic meters.
