Application of spectral decomposition in the lithologic reservoir exploration of Yueliangpao area,Songliao basin

The paper predicted the subaqueous distributary channels of delta front of Saertu oil layer in the Yueliangpao area,the west slope of Songliao Basin by spectral decomposition.And at the same time,by integrating with well-seismic reservoir inversion,sedimentary facies research and overlapping structural map,the study identified two favorable lithologic traps of Saertu oil layer.Moreover,studies showed that the spectral decomposition technique can predict subaqueous distributary channels of delta front,and it is an effective method to study sedimentary facies and predict lithologic traps in undrilled and less drilled areas.
