摘　　要：应用录井、测井、地质和地震资料,研究了松辽盆地南部月亮泡地区上白垩统姚家组萨尔图油层Ⅰ砂组的沉积微相,并采用沿层地震属性分析技术,分析了河道砂体的展布特征,利用拟合分析进行验证,结果表明萨尔图油层Ⅰ砂组沉积相为三角洲前缘亚相,其微相类型有水下分流河道、河口坝和分流间湾,已有的勘探成果也证实水下分流河道砂体是油气的有利聚集区,结合构造发育情况,预测了松辽盆地南部月亮泡地区构造岩性油气藏勘探的有利区带。Sedimentary microfacies on sandstone Group I of Sartu oil-bearing layer of the Upper Cretaceous Yaojia Formation at Yueliangpao area in the South of Songliao Basin are studied with logging, geological and seismic data. By using horizon seismic attribute analysis technology, the distribution characteristics of river sandstone bodies are researched. After fitting analysis, it is concluded that the sandstone Group I of Sartu reservoir is the delta front sedimentary and the sedimentary microfacies types of the major sand bodies are underwater distributary channel, mouth bar and bays between distributary channel sedimentary microfacies. The result shows that the distributary channel sand bodies were developed widely for oil and gas accumulation. Combining the structural development, the beneficial areas for structure-lithology reservoirs are predicted.
