由于地质找矿工作逐渐转向深部地层，以及石油和天然气钻井有采用超小口径的趋势，预计今后若干年内，深孔岩心钻机将会得到蓬勃发展。众所周知，石油或天然气钻井的口径比较大，所用钻具的规格和钻机能力都较大，钻进成本也较高。有人把钻进能力同样为1000m的地质勘探钻机和油井钻机作了对比，备项技术指标如表1。 Deep-hole core drilling rigs are expected to flourish in the next few years due to the gradual shift of geological prospecting work to deep strata and the ultra-small caliber of oil and gas drilling. As we all know, oil or gas drilling larger diameter, the use of drilling tools specifications and drilling capacity are larger, drilling costs are higher. Some people have the drilling capacity of the same 1000m geological exploration drilling rig and oil well drilling rig made a comparison, technical indicators listed in Table 1.
