摘要
深海底蕴藏着大量的矿产资源,海底资源的开发有助于缓解全球性资源匮乏的局面。深海岩芯取样钻机是进行深海底矿产资源勘探、地质调查等不可缺少的重大技术装备。总结了国外已开发深海底岩芯取样钻机的主要设计参数及特点,分析了国外不同钻机的实际应用效果以及发展趋势。研究发现,国外已经先后开发了多台深海底岩芯取样钻机,部分已经应用于深海钻孔取芯,但均存在不同程度的技术问题;经过曲折的研发历程,钻机的钻具以及钻进方法均得到优化,但仍存在取芯率不稳定且普遍偏低等问题。探究国外钻机设计技术及开发经验,以期为我国深海钻机的研发和改进提供参考。
There are a large number of mineral resources hidden in the sea-floor,and the development of seabed resources is helpful for easing the situation of global resource scarcity. The deep-seabed coring drills are major technical equipment for resource exploration,geological survey in seafloor et al. The designed parameters and features of foreign deep-sea coring drills were summarized; The result of actual application and the development trend of foreign Coring drills were analyzed.From the study,many foreign countries have developed sets of deep-seabed Coring drills,and some of them have been used in sea-floor core drilling,but exist some kinds of technical issues. The drill tool and drilling method have been optimized undergoing a hard time,but there are still some problems that coring rate is not stable and generally low. In order to provide powerful reference for developing and improving the deep-sea coring drills of China,it is necessary to research design technology and development experience of foreign drills.
