摘要
The reefs are special sediment and grow in the shallow sea environment.They are uniform in size and shapes and vary with the geologic climate and palaeogeography.Because of the acoustic wave impedance difference between the reef and wall rock,there are many features of reef in the seismic time profile such as events weakening,heaving,falling,and so on.The seismic data interpreter usually searches the reef by the features,but the abnormity of amplitude is affected by many factors,so it reduces the mission success rate of reefs exploration.This paper processes the abnormal data by spectral decomposition technology based on the short time fourier transform and continuous wavelet transform.The results are corresponding to drilling results and show the correctness and validity of this method.
