With the rapid development of the domestic petroleum industry, the variety of base oils has increased continuously, and production processes have been constantly improved. According to the classification of base oils in internationally accepted standards, this paper elaborates the specific definitions of various base oils, discusses their application directions and scopes, reviews the development process of their production technologies, and analyzes product classification and quality control from multiple perspectives such as performance indicators and molecular structure.
