摘要

Deep drilling for water, brine and minerals in the earth crustfollows the basic idea of drilling holes in wood or stones, which can be considered a basic skill of human beings used in all early cultures. The first significant publications covering only the drilling of wells through earth and rock layers, appeared in the 18' century. In the early 19th century drilling techniques became part of technical knowledge taught at higher schools. It was in this century, that many variations of the drilling process, of the used machineries and tools have been developed; out of this variety the rotary drilling process evolved, which dominates todays deep drilling. Deep drilling took advantage of the general development of technology, which exerted a push on drilling. On the other side the requirements of drilling for high quality materials and mobility of machineries exerted a pull on technology, too.
