【摘要】 石油物探地理信息系统是一种将地理空间信息同石油物探信息相结合的计算机应用工程系统。通过数据库存储与石油物探相关的数据和图形信息,实现物探信息的科学管理、动态查询和决策分析。在此围绕石油物探地理信息系统中数据库的建立,从物探数据模型、数据管理方法、工作流程、数据库结构等几个方面进行了探讨。根据物探数据种类多、数据量大的特点,提出了一种以项目为主线的数据管理方法;根据系统既有地理信息数据,又包含物探专题数据的特点,设计了一种科学的数据库结构;并强调了数据安全性的问题。更多还原

【Abstract】 Petroleum geophysical prospecting geographic information system(GIS) was a computer application system,which combined geographic information with petroleum geophysical information.Data and graphical information from geophysical prospecting were stored in database.Therefore,the system could be used to accomplish information management,dynamic inquiry and decision-making analysis.This article analyzed data-model,the method of data management,works flow,database structure on the establishing database of petroleum geophysical prospecting GIS.Data-model of application system was established based on real geophysical prospecting work.Because there were large amounts of various types of data in the geophysical prospecting work,the method of data management was advised.Considered the geophysical data including geophysical and geographical data,a scientific kind of database structure was designed.The security of data was emphasized in conclusion.更多还原
