矿产钻探的目的是对一个钻孔全部或局部提供地质资料。虽然一般认为呈固体岩心形态的样品最为理想,但对地质学家而言,在一些非固结地层或者当进度和成本显得很重要时,采取岩屑样品也是两种办法其中之一。不用取样而使用钻孔测井技术进行勘探 The purpose of mineral drilling is to provide geological data for all or part of a borehole. While it is generally accepted that samples that are in solid core form are ideal, for geologists, cuttings samples are also one of two options for some unconsolidated formations or where progress and cost are important. Drill well logging techniques are used for exploration without sampling
