华北油田三维地震资料品质分析数据库的开发及应用效果

Database Development for 3D Seismic Data Quality Analysis and Its Application in Huabei Oilfield

到2003年,华北油田三维地震勘探已经历了10多年,早期的地震资料由于受到技术和装备的制约,资料品质较差,有必要对老资料进行品质分析,对重新处理潜力做出评价,为二次三维采集部署提供依据。建立和完善原始地震资料品质分析及相关三维地震勘探数据库,开发数据库管理软件,实现地震勘探数据库的快速查询功能。针对华北油田生产特点,详细阐述了系统的开发原则与模式、系统总体设计、主要技术以及主要功能,通过资料品质分析,集成了地震资料采集、处理与品质分析等地震勘探数据、信息,并对华北油田二次三维采集中的应用效果进行了分析。

The 3D seismic exploration has been conducted in Huabei Oilfield for more than ten years till 2003.Restricted by techniques and equipments,the quality of old seismic data was poor.So it is necessary to conduct quality analysis on the old data and reevaluate the potential of new data processing,so as to provide basis for the arrangement of the secondary 3D acquisition.Besides,the databases for original data quality analysis and related 3D seismic exploration should be established and improved,as well as the database management software should be developed.The quick query function of the seismic exploration database will be fulfilled.In view of the production characteristics of Hubei Oilfield,the development principle and patterns,the general design,the major techniques and functions of the database system are discussed in details.Through data quality analysis,the data and information of seismic exploration are developed, integrating seismic acquisition,processing with quality analysis.What's more,the application of the database to the secondary 3D acquisition is analyzed.
