【Abstract】 The paper studied the cycle characteristics of theoretical model,gave the time frequency responses in different models and highlighted the discussion on design of time frequency filter and setting of display parameters,resulted in that the ideal results can be got if adopting triangular filter with frequency band of 1.2 octaves and the dominant frequency of 1.05 recursive ratios.The paper took the TN and QNQ work areas having different lithology as examples,highlighted the analysis of seismic cycle characteristics of sand mud reservoir and limestone reservoir,achieved good applied results.更多还原
