近几年来，随着钻探技术的迅速发展，其应用领域愈益广泛。首先，钻探仍是地质找矿的主要手段。工业的高速发展，人类物质文明水平的不断提高，对矿产资源的需求量不断增加；但易采掘的矿产储量却愈来愈少。钻探工作只能“上山”、“下海”、入沟”，向地球深部进军。苏联于1972年在科拉半岛开始施工的СГ-3钻井，已钻进十多年，还未钻到设计的15000m井深，耗费了大量财力物力，其主要任务之一就是为了探明地球深部是否存在矿产资源。
In recent years, with the rapid development of drilling technology, its application fields are increasingly widespread. First, drilling is still the primary means of prospecting for geology. The rapid development of industry, the continuous improvement of human material civilization, the increasing demand for mineral resources; but less and less mining reserves. Drilling can only “go up the mountain”, “down the sea” and into the ditch. "The Soviet Union started its construction on the Kola Peninsula in 1972. The СГ-3 well has been drilled for more than a decade and has not been designed yet 15000m deep, spent a lot of financial and material resources, one of its main tasks is to ascertain the existence of deep mineral resources in the earth.
