摘　　要：小波时频能量谱是在小波变换时频分析基础上 ,计算小波频谱能量。将小波变换时频能量谱技术与层序地层学理论相结合 ,以寻找不同类型沉积旋回与小波能量谱之间的对应关系 ,为地震层序的划分以及沉积相分析提供理论依据。通过对理论模型和实际资料的计算表明 ,小波时频能量谱方法分析研究沉积旋回体是可行的 ,可揭示地下沉积旋回体相关信息 。The time-frequency spectrum calculated by wavelet transform is called time-frequency spectrum of wavelet transform(TFSWT). In this paper, we combine TFSWT with stratigraphy in order to examine various relations between the sedimentary cycles and the characteristic of TFSWT, so as to provide theoretical grounds for the seismic sequences identification and sedimentary facies analysis. With calculation of theoretical models and real data, it shows that the method is more effective to analysis sedimentary cycle system. It may provide information on interior organization of sedimentary, and distribution of material component in sedimentary cycle systems.
