变偏移距提高分辨率地震资料叠加处理方法

On Improving the Resolution of Seismic Data Overlapping Processing by Changing Offset Distance

野外地震资料采集观测系统直接运用于提高分辨率地震资料处理,不仅忽略了观测系统与分辨率之间的关系,而且会影响分辨率效果的进一步提高。通过分析分辨率处理与地震信号频率范围的关系、分辨率与接收排列长度的关系,对比不同排列长度观测系统的分辨率处理效果,提出了变偏移距提高分辨率地震资料处理方法。

The field seismic data collecting and observing system is often used directly to enhance the resolutions of seismic data. However, the ideal resolution is undermined by the neglect of the relations between observing system and resolutions. In this paper, the relation between the resolution processing and seismic signal frequency range and the relation between the resolution and the length of receiver array are analyzed and the resolution processing results of observing systems in different lengths of arrays are compared and a new seismic data processing approach is put forward to improve resolution by changing offset distance.
