综述了国内外钻井液体系分类方法,介绍了分散介质分类方法、API和IADC钻井液分类方法,提出了按钻井液密度大小分类的新方法。按密度分类主要可分为5大类,包括密度小于1.0g/cm3的低密度钻井液、密度介于1.0~1.2g/cm3之间的普通钻井液、密度介于1.2~1.6g/cm3之间的普通加重钻井液、密度介于1.6~2.3g/cm3之间的高密度钻井液、密度大于2.3g/cm3的超高密度钻井液。根据密度对钻井液体系进行分类,有利于钻井液体系的选择与使用。

The classification methods of drilling fluid systems are reviewed and illustrated, e.g., dispersing medium classification, API classification and IADA classification. A new classification method based on drilling fluid density is presented, and five categories can be classified by this method, which covers drilling fluid of low density of less than 1.0 g/cm3, drilling fluid of ordinary density of less than 1.2 g/cm3, drilling fluid of ordinary weighted density of 1.2~1.6 g/cm3, drilling fluid of high density of 1.6~2.3 g/cm3, and drilling fluids of ultrahigh density of more than 2.3 g/cm3. This method is easy for drilling fluid selection and field using.
