摘　　要：利用频谱分解技术,预测松辽盆地西斜坡月亮泡地区萨尔图油层三角洲前缘水下分流河道砂体;结合储层反演、沉积学及储层地质学研究,编制沉积微相平面图,识别2个规模较大的断层-岩性圈闭;通过对频率切片的振幅平面变化分析及井震标定,发现频率为20Hz的调谐振幅可揭示萨尔图油层顶部砂组砂岩厚度的变化.研究结果表明,频谱分解技术可以预测三角洲前缘水下分流河道砂体,是无井区和钻井稀疏区开展精细沉积微相研究及岩性圈闭预测的一种技术手段.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.
