Application of High-accuracy Time-frequency Analytical Method in Predicting Reef Reservoirs

It was important of time-frequency analytical technique in predicting reservoir,and in expressing the seismic information in time domain and frequency domain at the same time.The seismic information was expressed in time-frequency domain,and was not expressed in time domain.High-accuracy time-frequency analysis method S-transform was selected because traditional time-frequency theory could not overcome the difficult and develop time resolution and frequency resolution difficulty.The flow applying S-transform time-frequency analysis method is discussed as it is used for predicting organic reservoirs,and the result is in accordance with actual drilling.
