奇异性分析方法在地震资料解释及反演研究中的应用

本文引入启动函数拓展传统的地层转换模型,在该模型中利用奇异性信息量化地层速度的突变特征,并基于传统的褶积模型研究奇异性信息在波阻抗到合成地震记录之间的传递性.研究结果表明,地震记录中较好地保留了地层介质的奇异性特征,因而从地震记录中提取的奇异性信息除了可以帮助进行地震解释外,还可以作为介质波阻抗反演的有力的支持工具.

Applications of singularity analysis to seismic data interpretation and inversion research

In this paper, we introduce the onset function to generalize the traditional geologic boundaries variations model which uses, singularity information to represent the abruptness of the lithologic velocity transition. We study the singularity information passage from acoustic impedance to seismogram based on the convolution seismic-model theory. Our results indicate that stratum singularity information is preserved well by seismic data, so it is a powerful tool for delineating stratigraphy boundaries and inversing acoustic impedance based on singularity analysis of seismic data.
