摘　　要：地质岩心钻探是探明地层含矿储量最直接、最有效的手段,所取出岩心是研究和了解地下地质和矿产情况的重要实物地质资料。地质岩心钻探常用的取心工艺基本为单管干钻卡心钻进工艺与绳索取心钻进工艺,但均对地层岩性有一定的要求,在部分难取心地层适用性较差。本文主要通过结合绳钻工艺和普钻工艺的共同优点,将绳索取心钻具应用至普钻工艺中,并经过现场应用确定此取心钻进方法在提高岩心采取率方面具有积极的作用。Geological core drilling is the most direct and effective means to explore the reserves of strata containing ore,and the core extracted is an important physical geological data for studying and understanding underground geology and mineral resources.At present,the coring technology used for core is mainly wire-line coring drilling and the trip coring drilling,but both of them have certain requirements on formation lithology,and their applicability is poor in some difficult strata.In this paper,by combining the common advantages of rope drilling technology and common drilling technology,the wire-line coring drilling tool is applied to the trip coring drilling,and through field application,it is determined that this method of coring drilling has a positive role in improving the coring rate.
