本文介绍了基于ORACLE关系型数据库,采用以文件系统辅助数据库管理的集成化技术和遵循图文数据库的基本思想,建立油田勘探开发图形库的方法以及对图形(像)数据库查询、操作、维护等管理功能的实现。在油田勘探、开发工作中一项基本的、必不可少的、也是占用精力和时间最多的任务是编辑、绘制图形或拍摄图象。收集资料离不开它、分析问题离不开它、成果答辩离不开它。因此图形(象)库的建立及其自动处理,是一件迫切需要解决的问题。我们与黑龙江大学信息技术研究所协作经过两年的努力,初步建立起包括二十八种图形的勘探、开发图形库及其管理系统,并逐步推广使用。这是一个关系型数据库系统与文件系统相结合的集成式管理系统,用户在统一的环境下管理图形属性数和图形(象)数据。
This article describes the ORACLE relational database, the use of file system-assisted database management integration technology and follow the basic idea of graphic database, the establishment of oil exploration and development of graphics library methods and graphics (image) database query, operation, maintenance, etc. Implementation of management functions. A fundamental and indispensable task in oil and gas field exploration and development is to edit, draw or photograph images. It is inseparable from the collection of information, analysis of the problem can not be separated from it, the answer is inseparable from the results. Therefore, the establishment of graphics (image) library and its automatic processing is an urgent problem to be solved. After two years of hard work with the Institute of Information Technology of Heilongjiang University, we initially established a graphic library of exploration and development including 28 kinds of graphics and its management system and gradually promoted its use. This is an integrated management system that combines a relational database system with a file system to manage graphical attributes and graphics (image) data in a unified environment.
