| 摘 要： | 基于S变换的时CD*2]频局部化思想，采用可灵活选择窗函数的广义S变换，以实际地震子波代替常规S变换中的基本小波，系统地研究了广义S变换在地震高分辨处理中的应用，并首次提出了基于广义S变换的高分辨剖面。仿真实验和实际资料的处理结果均说明广义S变换在地震高分辨处理方面的可行性和有效性，由此得到的高分辨剖面不仅有效地提高了地震波的主频，而且可以通过提取单频曲线或单频剖面，细致地研究局部构造的层位信息，为地震资料处理和解释提供了一种有效的工具。

| Abstract: | Based on the local spectrum of S transform, this paper systematically studied the application of generalized S transform in seismic high resolution processing by replacing the mother wavelet in S transform with real seismic wavelet, and initiates the concept of seismic high resolving profile based on GS transform. Results of theoretical and practical experiments show the feasibility and validity of seismic high resolution processing with GS transform. The resulting profiles are of spread dominant frequency of seismic waves, and the curve or profile of single frequency can be used to study the horizon information of local structure, which provides an effective tool for seismic data processing and interpretation. |
