海洋地质十七号船及其在海岸带地质调查中的应用

Marine Geology No. 17 Vessel and its application in coastal geological survey

摘要:

海岸带地质调查对于了解我国沿海地区资源分布和生态环境状况、推动城镇化发展、保障经济可持续增长以及应对频发的自然灾害具有至关重要的意义。海洋地质十七号船是由我国自主设计、建造的小吨位海岸带综合地质调查船，填补了我国该领域的空白，提升了我国海岸带地质调查能力。该船的钻探系统针对不同地层配套多套取心钻具，并针对海岸带钻探作业特点，制定安全应急措施，顺利完成了北黄海西部海域一个140 m深钻孔的钻探任务，岩心采取率达92.7%。实践证明，海洋地质十七号船钻探系统可圆满完成海岸带地质调查钻探取心任务。

Abstract:

Coastal geological surveys play a pivotal role in understanding resource distribution and ecological conditions in China''s coastal regions， promoting urbanization development， ensuring sustainable economic growth， and addressing frequent natural disasters. The Marine Geology No. 17 Vessel， independently designed and constructed by China， is a small-displacement integrated coastal geological survey vessel. It fills a critical gap in China''s capabilities in this field and significantly enhances the nation''s coastal geological survey capacity. The vessel''s drilling system is equipped with multiple coring tools tailored to different stratigraphic layers， and emergency safety protocols have been established specifically for coastal drilling operations. The system successfully completed a 140m deep drilling task in the western waters of the North Yellow Sea， achieving a core recovery rate of 92.7%. Field applications have demonstrated that the drilling system of the Marine Geology No. 17 Vessel can effectively fulfill coastal geological survey drilling and coring missions.
