| 中文摘要:海底硬岩是世界大洋钻探实现“莫霍钻”目标必然钻遇的地层。世界大洋钻探实施的航次中已多次钻遇海底硬岩，不仅采获了岩心样品，也在钻进施工中发现了诸多问题。本文搜集了近年来世界大洋钻探实施的309、312、335、360和384等有关海底硬岩钻探航次的资料，在对航次情况简要介绍的基础上，重点阐述了目前海底硬岩钻探在钻头、井壁稳定以及取心工具等方面遇到的挑战以及采取的应对措施，并对今后海底硬岩钻探的发展进行了展望。 |

| Abstract:Subsea hard rock is the stratum that ocean drilling will inevitably encounter to achieve the goal of “Moho Drilling”. During the many ocean drilling expeditions， hard rock were encountered subsea many times. Not only have core samples been collected， but also many problems have been discovered in the drilling operation. This article collects data on subsea hard rock drilling expeditions in ocean drilling carried out in recent years， including 309， 312， 335， 360 and 384. A brief review of the expeditions is made with focuses on the challenges encountered in the current subsea hard rock drilling in terms of drill bits， wellbore stabilization and coring tools， as well as the solutions； and a prediction is also made of the development of subsea hard rock drilling in the future. |
