| 中文摘要:海域固体矿产资源勘探、开发是海洋开发和利用的重要组成部分。本文主要从钻探设备、工艺、安全等方面对海域地质岩心钻探工程技术进行分析，总结了相关技术措施：一是除依据地质要求选择常规钻探设备外，要依据海域环境特点，选择安全可靠的钻探平台；二是钻孔结构设计、钻进方法、冲洗液等均应符合海域特点和要求；三是必须坚持安全第一原则，编制安全应急预案等。通过山东莱州三山岛北部海域金矿勘探项目应用实例，证实了海域地质钻探工程技术的适应性。 |

| Abstract:Exploration and development of marine solid mineral resources is an important part of marine development and utilization. Some technical measures were summarized and discussed on drilling projects in shallow waters from drilling equipment, technology, safety, etc. First, it is necessary to choose a safe and reliable drilling platform based on the characteristics of the marine environment，in addition to selecting conventional drilling equipment based on geological requirements. Second, the drilling structure design, drilling method and washing fluid should be carried out according to the characteristics and requirements of the sea area. Third, we must adhere to the principle of safety first and compile safety emergency plans. Through the application example of the gold exploration in the northern sea area of San Shandao, the adaptability of marine geological drilling engineering technology has been proven，it provided some experience references for related shallow sea geological drilling projects. |
