　　润滑油基础油主要分矿物基础油、合成基础油以及生物基础油三大类。矿物基础油应用广泛，用量很大（约95%以上），但有些应用场合则必须使用合成基础油和生物油基础油调配的产品，因而使这两种基础油得到迅速发展。

　　矿油基础油由原油提炼而成。润滑油基础油主要生产过程有:常减压蒸馏、溶剂脱沥青、溶剂精制、溶剂脱蜡、白土或加氢补充精制。1995年修订了中国现行的润滑油基础油标准，主要修改了分类方法，并增加了低凝和深度精制两类专用基础油标准。矿物型润滑油的生产，最重要的是选用最佳的原油。

　　Lube oil base oil is mainly divided into mineral base oil, synthetic base oil and biological base oil three categories. Mineral base oils are widely used in many fields, and their usage is very high (about 95% or more) , but in some applications, synthetic base oils and bio-oil base oils must be used. The base oil of mineral oil is refined from crude oil. The main production processes of Lube base oil are: Atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing, clay or hydrorefining. In 1995, the current Lube Base Oil Standard in China was revised, mainly by modifying the classification method, and adding two special base oil standards of low pour point and deep refining. In the production of mineral lubricating oil, the most important thing is to choose the best crude oil.
