[0002] Petroleum, one of the main objects of geological exploration, is a viscous dark brown liquid, known as the "blood of industry". Petroleum is stored in some areas of the upper crust, and its main components are a mixture of various alkanes, cycloalkanes and aromatic hydrocarbons. At present, petrochemical agents are often needed to assist in the extraction of petroleum, such as chemical plugging removers, iron ion chelating agents, profile control agents, etc.
