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.
