Using multi-parameters analysis of seismic information to evaluate lithologic traps in continental basins

The lithologic traps in continental basins are characterized by complex boundary condition,irregular shapes,subtle occurrence,complex accumulation and various migration mechanisms,and the features of itself are of small area,thin reservoir and occurring in group.According to all these characteristics,it is proposed that the selection of seismic data,calibration of horizon and reservoir,interpretation of top and bottom controlling horizons and determination of time window are the key factors for the lithologic traps identification,optimization,description and evaluation with multi-parameters analysis of high-resolution 3D seismic.The multi-parameters analysis methods include seismic facies classification,seismic inversion and reservoir prediction,seismic attributes analysis,fluid potential analysis,hydrocarbon detection and 3D visualization.Since the lithologic reservoir exploration is at the beginning stage,the related technological specifications and criterions are still need to be improved.
