摘　　要：深海岩芯取样钻机是开展海洋地质调查和海洋矿产资源勘探所必备的重大技术装备.2003年我国研制成功第1台深海浅地层岩芯取样钻机并连续多年成功应用;2009年研发成功采用铠装光电复合缆向海底进行大功率长距离输电和光纤通信的深海2米岩芯钻机.但该型钻机由于钻进深度有限,无法对深海热液硫化矿藏进行勘探.本次研发的深海底中深孔岩芯取样钻机首次海试成功并取得样品.介绍了钻机的基本功能与结构、主要技术指标、技术难点、海上试验情况等.深海底中深孔岩芯取样钻机的研制成功使我国在这一领域的技术水平得到大大提升.Currently, the core sampling drill secures a crucial position in oceanic geological survey and mineral resource exploration. In 2003, the first deep-sea and shallow strata core-sampling drill was domestically developed. In 2009, the 2m deep-sea core-sampling drill was developed using armored electro- optical cable for long-distance power transmission and fiber communication. Due to the limitation of drilling depth,the deep-sea hydrothermal sulfide deposits cannot be explored by this drill. Accordingly, a new core-sampling drill is successful developed for offshore testing. In this study, the basic functions and structure, major specifications and imperative and offshore testing conditions are introduced. Therefore, this approach significantly enhance the technological level in this area.
