(一)苏联正广泛使用CCK和KCCK型绳索取心钻具和—100型水力输送岩心的钻探装置。绳索取心钻进的钻速较一般钻进方法钻速提高1.5—2倍,并可提高岩心质量。水力连续输送岩心钻进法与一般钻进法相比可提高钻速3—4倍。
(1) The Soviet Union is widely using CCK and KCCK type rope coring tools and -100 type hydraulic transport core drilling equipment. Cord Coring Drilling ROP ROP 1.5-2 times faster than normal drilling and improves core quality. Hydraulic continuous drilling core drilling method compared with the average drilling method can increase the drilling speed 3-4 times.
