摘要
地震反射波的波形含有极为丰富的地下地质信息。同一界面的反射波具有相似的波形特征。据此,本文分析了反射波的外形特征,建立起适于地震波形的符号描述法——树表达式。提出了利用树间距离对比反射波组,实现地震层位的自动追踪,试算结果表明方法的效果良好。文章最后还讨论了本方法的不足之处,并指出其应用前景。
Rich and varied underground geology information is involved in reflection seismic waveforms. Reflections come from the same reflector are similar in their waveforms. On this ground, we have made an analysis for the reflection waveform and a symbolic notation suitable for describing the seismic waveform--THE TREE REPRESENTATION, was
thus established. A new method of event correlation and auto-seismic horizon tracing by using the distance between branches of the tree was presented. Tested resultant is very good. At the end of this paper, the deficiencies of the technique and the trend of its application were also discussed.
