基于广义S变换的地震资料处理

Application of Generalized S-transform in Seismic Data Processing

在实际地震资料处理中,其地震数据处理成果会影响后期解释的准确性和可靠性,由于受到各种环境,复杂地形因素的影响,其处理结果导致实际地震分辨率不是很高,品质不好,不适用于后期的构造解释和储存预测。本文是基于S变换的原理,通过改变S变换窗函数的算法,提高时频分辨率,以薄互层模型为基础,在实验中通过各种不同时频分析方法的对比研究,以及对处理实际问题中得到结果进行分析对比,最后得出广义S变换在地震资料处理相比中提到的其他方法更具有明显的优势。

In the actual seismic data processing,seismic data processing results will influence the correctness and reliability of interpretation,due to various environmental factors,effects of complex terrain,the processing result of real seismic resolution is not very high,the quality is poor,is not conducive to structural interpretation and prediction of the late storage. This paper is based on the principle of S transform,by changing the S transform window function algorithm to improve the time-frequency resolution,with thin layer model as the foundation,in the experiment by using different time-frequency analysis methods and comparative study,in dealing with actual problems in the analysis of the ratio,finally the generalized S transform in the seismic data processing method of time-frequency analysis method mentioned in other than the more obvious advantages.
