我局目前开动小口径钻机十五台,其中以金刚石钻进为主的十三台。勘探矿种有铜,钨、铅锌、锡等,由于钻孔深度为600至1000米,所以多数机台使用JU-1000型钻机,此外,还有我省自己研制的JYP-1000型小口径转盘钻机及XU-600-3型钻机。小口径钻进以56毫米为主,几乎全部采用双管钻进。多数选用人造孕镶金刚石钻头,少量使用天然孕镶或表镶钻头。一般情况下用清水乳化冲洗液钻进,见复杂地层后才换用低固相泥浆。
Our bureau currently operates 15 small-diameter drilling rigs, of which 13 are diamond-based drilling. There are copper, tungsten, lead, zinc, tin and other exploration minerals, because the drilling depth is 600 to 1000 meters, so most machines use JU-1000 drilling rig, in addition, there are our own developed JYP-1000 small caliber Turntable rig and XU-600-3 drilling rig. Small diameter drilling to 56 mm, almost all using double pipe drilling. Most of the selection of artificial impregnated diamond drill, a small amount of natural impregnated or table set with drill bits. Under normal circumstances with water emulsion rinsing liquid drilling, see the complex formation of low solid mud.
