TB级海量地震数据三维显示系统的设计与实现
|
摘要
随着渤海海域油气勘探开发的不断发展,地震数据体的数据量在不断增加,可达到几百GB甚至TB级,而现有软件无法完成跨工区、跨软件的海量地震数据调用和显示。自主研发了TB级海量地震数据三维显示系统,通过建立网络数据服务对多个现有专业软件数据库、多个工区的地震数据统一调配,以形成一个庞大的数据集并提供统一的数据访问接口,最终在客户端实现海量地震数据的实时高速读取,并以各种方式(剖面、切片、三维体)显示地震数据及相关成果图。应用效果表明,该系统功能强大、方便快捷,不仅可以在工作站上调入总量达到TB级的多个地震工区数据,同时还可以在PC机上快速浏览数据量达到几十GB的地震体,从而为渤海海域区域地质研究提供有力的技术支持。
With the continuous hydrocarbon exploration and development in Bohai water,the seismic data volume is expanding continuously and may be up to a level of several hundred GB or even TB.However,the existing softwares cannot call and display the mass seismic data from various work areas and softwares.A 3D display system of the mass seismic data with a TB level has been independently researched and developed,in which the multiple existing databases of special software and the seismic data from multiple work areas are allocated in a unified way by creating the service of network data,in order to form a huge data set and provide a unified data access interface,to achieve a real-time and high-speed access to the mass seismic data at a client end and finally to display the seismic data and their related figures in various ways(section,slice and triaxiality).Its applications have shown that this system is powerful in functions and easy and fast in exploitation,and can not only call seismic data up to a TB level from several work areas at a workstation,but also view quickly the seismic bodies with data up to several ten GB at a PC.Therefore,the system may provide powerful supports for studying regional geology in Bohai water.
