Application of Time-frequency Analysis Method in Extracting Acoustic Logging Information
Chengguang Zhang · Journal of Jianghan Petroleum Institute · 2005
During the acoustic logging data process,the information of time-frequency of related spectral component can not be provided generally by means of Fourier Transformation(FT).The method and theory of time-frequency analysis based on short-time Fourier Transformation are studied and the wave arrival points of easy component are determined by making software and using time-frequency analysis.The results show that the method of time-frequency analysis can be used to extract acoustic logging data for solving the practical problems related to time and frequency.
