| 摘 要： | 本文在总结国内外地震勘探解释系统的基础上,以物理地震学为理论基础,利用谱分解、地震信号处理中的偏移技术、模式识别中的分级聚类算法和最小二乘法,提出了自动提取断棱衍射、识别断层的思想.仿真结果表明该思想和方法是可行的.本方法还可用于岩性地球物理勘探.

| Abstract: | A new idea of recognizing faults is proposed in this paper. Spectrum decomposition is used to seperate diffractions and noise from uncliffracted reflections. Migration is used to seperate diffractions from noise. Then hierachical cluster analysis is used to gather fault points that belong to the same fault plane. Lastly, least-square algorithm is used to fir fault planes to the extracted fault points. Fault planes were successfully fitted to synthetic data by the computer MV/6000. Possible applications of this method in seismic stratigraphy was also discussed. |
