本文以油气综合勘探数据库结构为例，探索ＳＥＤＢＡ数据库结构的调整和功能扩展的可能性。新的ＳＥＤＢＡ是将现行ＳＥＤＢＡ结构的第二层次中的煤及ｚＳＫ４专用数据库及含金属质沉积岩专用数据库改为煤炭专业数据库和金属与非金属矿藏专业数据库，与新增加的石油地质专业数据库一并置于第二结构层之下，构成新的第三层结构一专业数据库结构层。并将原来第三结构层中的１４种实验表作为各专业数据库的一个子数据库，组成新的ＳＥＤＢＡ数据库结构。显然，新的ＳＥＤＢＡ不仅包含了所有的沉积岩石学信息，还容纳了各种沉积岩矿产资源（如石油地质等）的数据库系统，拓宽了ＳＥＤＢＡ的应用前景。石油地质工作者应用新的ＳＥＤＢＡ能系统地进行盆地分析、油藏描述和油藏数值模拟等地质问题研究，以及模拟地质过程，检验地质现象，揭示动态演变，预测未知区域；还可与全球ＳＥＤＢＡ联网，进行区域和洲际比较研究，促进信息的交流和共享。
In this paper, taking the structure of integrated oil and gas exploration database as an example, we explore the possibility of adjusting and expanding the function of SEDBA database. The new SEDBA is to change the existing coal-based and zSK4-specific databases and metal-bearing sedimentary rocks specialized databases in the second tier of SEDBA structure into coal professional databases and specialized databases for metal and non-metallic mineral deposits, together with the newly added database of petroleum geology Placed under the second structural layer, constitute a new third layer structure of a professional database structure layer. And the original third structure layer of the 14 kinds of experimental tables as a professional database of a sub-database to form a new SEDBA database structure. Obviously, the new SEDBA not only contains all the sedimentary petrology information, but also contains a variety of sedimentary rock mineral resources (such as petroleum geology, etc.) database system, broaden the SEDBA application prospects. Using the new SEDBA, petroleum geologists can systematically study geological problems such as basin analysis, reservoir description and reservoir numerical simulation, as well as to simulate geological processes, examine geological phenomena, reveal dynamic evolution and predict unknown areas, and can also cooperate with global SEDBA Networking, regional and intercontinental comparative studies to promote the exchange and sharing of information.
