基于WEB—GIS的油气资源评价数据库构建及应用

Establishment and application of WEB-GIS based oil and gas resource evaluation database

在调研国内外油气资源评价数据库研究现状的基础上,针对石油公司层面的评价需求,通过优化已有常规数据结构、新增非常规数据结构,重新构建了基于WEB—GIS的数据库结构体系并研发了相应的数据库管理系统。系统采用"数据库层"、"数据库服务层"、"业务应用层"和"表示层"的4层体系结构,包含GIS功能、数据管理、查询检索、统计分析、成果管理、数据接口和系统管理等主要功能,以B/S方式和GIS技术管理常规油气资源和致密油、致密砂岩气、页岩气、煤层气、油砂矿、油页岩和天然气水合物等7种非常规资源的评价数据、图件和文档。系统应用于中国石油第四次油气资源评价,有效支撑了各油田资源评价工作,同时积淀了宝贵的数据资源,为今后的油气资源动态评价工作奠定了基础。

After investigating the research status of oil and gas resource evaluation database at home and a- broad, the structural system of WEB-GIS based database was reconstructed according to the evaluation re- quirements of oil companies by optimizing the existing conventional data structure and adding new uncon- ventional data structure,and the corresponding database management system was developed.The system is a four-layer structure, including ＂database layer＂, ＂database services layer＂, ＂business application layer＂ and ＂presentation layer＂.The system can fulfill functions such as GIS function, data management, Query and retrieval, statistical analysis, result management, graphic management, data interface and system man- agement. In this system, the evaluation data, drawings and documents of all conventional oil and gas re- sources and 7 unconventional oil and gas resources （tight oil,tight sandstone gas,shale gas,coalbed meth- ane,oil sand,oil shale and gas hydrate） are managed based on B/S mode and GIS technology.The system was applied to P etroChina＇s fourth oil and gas resource evaluation,providing effective support for resource evaluation of oilfields.In addition,valuable data were obtained,laying a basis for the dynamic oil and gas re- source evaluation in future.
