摘要
金刚石岩心钻探技术在国内的地质勘探领域中占据重要地位,是地质钻探工作中的关键技术。本文介绍了金刚石岩心钻探施工的主要内容和其施工工作要求,明确了该施工技术所具备的高钻速、孔壁间隙值小、施工产生的岩粉颗粒小且数量少等工艺特点,并结合其在地质勘探中的实际应用对技术进行了分析,对于岩心钻探施工人员具有参考意义。
Diamond core drilling technology in domestic has an important position in the field of geological prospecting,geological drilling work is the key technology in this paper introduces the main content of the diamond core drilling construction and its construction work requirements,clear the construction technology of the high rate of penetration hole wall small gap value construction of rock powder particles and process characteristics,such as less quantity and combined with its actual application in geological exploration of technology are analyzed,and has reference meaning for core drilling construction personnel.
