EXPANSION AND APPLICATION OF SEDBA

In this paper,a case on the structure of oil-gas exploration and development database was proposed so as to discuss the possibility for adjusting structure and functions of existing SEDBA database. The characteristics of new SEDBA database is that the specialized data sheets for coal/lignite,and metalliferous deposits in SEDBA are replaced by Coal Specialized Database and Metal/Nonmetal Specialized Database,and a new specialized database for petroleum geology is supplemented. The new SEDBA will contain the information not only about sedimentary petrol-ogy,but also about oil-gas and mineral resources,which can be used for basin analysis,pool de-scription,pool numercal simulation,etc.
