A brief review for twenty five years of Deep Sea Drilling Project and Ocean Drilling Program(DSDP/ODP)was made in present paper. It is believed that the scientific ocean drilling has been the cradel of the modern geoscientific thought and global geology. About 182 km of deep sea cores recovered from the drilling of every ocean have verified directly the theory of global plate tectonics

carried within itself the newly-emerged geoscience branchpaleoceanograhpy

and provides a great quantities of information for such fundamental geoscience problems as the global changes

the high-resolution global stratigraphy

the deep ocean sedimentology

the global events and the origin of hydrocarbon resources in the world's oceans. Finally

brief prospects for the 21st century's ocean drilling program is discussed as well.
