Abstract:As far as continental thin reservoir is concerned,the current seismic resolution is difficult to meet the needs of oilfield development.Obviously,only breaking through 1/4 wavelength limit in the common seismic exploration theory,it has possibility for using seismic exploration methods to study the issues in exploration and development of China continental thin reservoirs.In view of the issue and on the basis of hi-fi processing studied by the predecessors,the author presented the processing ideas of relatively preserving amplitude,frequency,phase and waveform under the condition of eliminating near-surface influence and the labeling by reference marker as well as a set of technical ideas of continuous detection of seismic attributes and dynamic interpretation based on reference marker.The author considered that the spatial change in thin-reservoir information less than 1/4 wavelength could be identified by interpretation of spatial difference in dynamic seismic attributes.The successful application of the technical ideas to many oilfields in China showed that using the set of technical ideas of identifying thin reservoir can gain sedimentary evolution information of thin reservoir less than 1/4 wavelength,and further form a model of"seismic analysis of reservoir evolution".The difference between seismic analysis of reservoir evolution and lithological seismic exploration is further discussed in the paper and difference and link with sequence-stratigraphy are also discussed.On that basis,the paper systematically discussed the applied mechanism of seismic analysis of reservoir evolution and practical applied results.
