摘要
广角地震可以在常规地震所无法解决的无记录和差记录区进行,完成地壳深部的调查研究.迄今已完成几万公里的测线任务.为了更好地处理广角地震数据,应采用一些特殊的处理手段,获取高质量的成像剖面,更好地服务于勘探开发.本文在介绍广角地震国内外发展现状的基础上,着重阐述了广角反射、折射中一些关键技术及存在的问题,并做了展望.
The research in the zones of no or weak record and investigation of lithosphere mainly uses wide-angle reflection and refraction seismic. In order to improve the processing quality of large offset seismic datasets, we can use some unique processing methods, such as non-hyperbolic NMO and corridor stack, etc. This paper mainly discussed some key techniques in wide\|angle reflection and refraction seismic and some existing problems based on the introducion of the progress of wide-angle seismic.
