[0002] Petroleum, one of the main targets of geological exploration, is a viscous, dark brown liquid, often referred to as the "blood of industry." Petroleum is stored in parts of the upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. There are two theories regarding the formation mechanism of petroleum: biogenic sedimentation and petrochemical formation. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material for many chemical industrial products, such as solutions, fertilizers, pesticides, and plastics.
