海上钻探施工离不开钻探平台的支撑。三山岛北部海域金矿钻探施工采用山东省第三地质矿产勘查院自主研发的海上钻探平台，目前已完成钻探工作量达12万米，最大钻孔深度达1 973.46 m，在海域岩金勘查领域具有重要意义。结合海上钻探工程实施情况，介绍了钻探平台的安装和拆卸作业，并重点对钻孔结构、钻进方法、金刚石钻进参数及冲洗液等工艺技术进行了系统研究，提出确保钻探工程顺利实施的若干质量保证措施，形成了一套完整的适用于浅海海域固体矿产勘查钻探工程的技术方案，为类似浅海钻探项目提供一定的技术参考。

With the gold exploration in the northern sea area of Sanshandao，the amount of offshore drill working  reached 120 thousand meters which was significance to solid mineral drilling.The construction of offshore drilling could hardly do with the offshore drilling platform.In view of the engineering actual situation， the simple offshore drilling platforms were used which developed by ourselves.With the drilling technology including hole structure， drilling fluid and so on and a series of drilling quality assurance measures，a whole technical solution applicable to offshore solid mineral exploration drilling engineering was formed that ensured the smooth operation of the drilling engineering.A large number of geological offshore drilling finished while the maximum boring depth was 1 973.46 meters. At the same time，it could provide technical reference to the similar offshore drilling projects.
