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

This paper discusses three-dimensional seismic exploration, a new technique in oil seismic exploration, and it needs heavy and complicated processing of surface survey data. Hence, it is the authors' 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. The authors detail 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{sup 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.
