| Abstract: | Gradually finding its place in seismic exploration in recent years, the wavelet transform attracts more and more attention for its good localization of time and frequency. Based on the theoretical analysis of wavelet and combined with the frequency-shared method, the ratio of high-frequency amplitude to lowfrequency amplitude is extracted as a characteristic parameter for the detection of oil and gas. By trial and error, the results show that the extracted wavelet parameter is a preferable seismic characteristic, and can be practicably used to predict oil and gas in the Sulige gas field. |
