三维石油地震勘探测量数据综合处理系统

三维地震是新兴的一种石油勘探方法,这种方法的测量数据处理工作量很大,计算也较复杂。因此,在微机内存、计算速度均有限的情况下,如何快速而有效地处理三维地震测量资料,是目前人们普遍关心的研究课题。本文详细介绍了在微机上开发的三维石油地震勘探测量数据综合处理系统。该系统能完成从野外数据采集到室内的数据计算、成果报表、平面图、断面图的自动打印输出。若方案设计周密,一次可处理800km~2的三维地震勘探测量资料。整个处理系统是交互式的人机对话系统,操作方便、选择性强、安全可靠。此系统已在准噶尔盆地三维地震勘探测量资料处理中投入使用,所获得的处理成果符合各项设计指标要求,资料的处理成本低廉。

Comprehensive processing system for surface survey data in three-dimensional oil seismic exploration

Three-dimensional seismic exploration is a new technique in oil seismic exploration, and it needs heavy and complicated processing of surface survey data. Hence,it is our interested problem how people can efficiently process the surface survey data in three-dimensional seismic exploration in the case of limited internal storage and low calculation speed of a personal computer. We details the personal-computer processing system for surface survey data in three-dimensional oil seismic exploration. This system can be used to accomplish both data acquisition and calculation to automatically output result data table, terrain map and cross section. If procedure is designed reasonably, this system can each time process the surface survey data in 800 km~2 three-dimensional seismic grid. The data processing system is interactive, convenient,adaptable and reliable. The system was used to process the surface survey data in three-dimensional seismic exploration in Zhengeer basin. The processed results satisfy design requirements. The processing cost is cheap.
