| 摘 要： | 时频分析方法经历了富氏变换、短时富利叶变换、小波变换三个阶段。随 改进，其在地学中的应用及研究范围也在不断拓宽，从对有关地质信号的能量补偿、滤波、压缩等处理，发展到通过信号的时频特征对地层的变化特征、沉积旋回性质等方面的研究。主要阐述了时频分布的概念，方法的改进及其在石油地球物理勘探中的应用和前景。

| Abstract: | The development of time-frequency analysis has three periods: Fourier transform, short-time Fourier transform, and wavelet transform. With the progressing of the time-frequency, the scale of its application is more and more extensive, from the signal processing to the striatgraphic character analysis. This theory describes the concept, the mothed and the development of time-frequency analysis and the application and future in the oil geophysical prospect. |
