在岩土工程中，钻井液用于协助地面钻孔的钻探，一般用于开采钻机对石油和天然气井的钻探中，钻井液还用于简单钻孔，例如水井。液体钻井液常被称为钻井泥浆。钻井液的三大类分别是水基泥浆(可分为打散和未打散)、非水泥浆（一般称为油基泥浆）和气体钻井液，其中可用多种气体。 钻井液的主要功能是提供液体静压力，防止地层流体进入井道，保持钻头冷却、清洁，回收岩屑和当钻探暂停的时候或钻具套装进出钻孔的时候悬浮岩屑，钻井液的特殊作用是防止油层损害并阻止腐蚀。
In geotechnical engineering, drilling fluid is used to assist in the drilling of surface boreholes. It is generally used in the drilling of oil and gas Wells by drilling RIGS. Drilling fluid is also used for simple drilling, such as Wells.Liquid drilling fluid is often called drilling mud.The three main types of drilling fluids are water-based mud (which can be divided into dispersed and undispersed), non-cement mud (commonly known as oil-based mud), and gas drilling fluids, of which several gases are available.
The primary function of the drilling fluid is to provide hydrostatic pressure to prevent formation fluids from entering the well, to keep the drill bit cool and clean, to recover cuttings and to suspend cuttings when drilling is suspended or when the drill string comes in and out of the hole. The special purpose of the drilling fluid is to prevent reservoir damage and prevent corrosion.
