摘　　要：地震数据体中含有丰富的地下地质信息,运用地震属性和沉积相分析相结合的方法,可以更为准确地识别河道砂体和有利储层。综合应用单井相分析及储层岩性标定、构造精细解释及地震属性分析、沉积相分析等方法对临江南地区扶余油层的沉积相进行了详细研究,认为扶余油层的沉积相类型为曲流河相和浅水三角洲相;砂体主要富集在研究区的西北部和东南部,中部主要沉积泥岩。Since seismic data volume contained abundant underground geological information,the method of seismic attributes combined with sedimentary facies was used to more accurately identify the channel sand body and favorable reservoirs.The methods of single well facies analysis,the reservoir lithologic calibration,fine structural interpretation,seismic attribute analysis and sedimentary facies analysis were used to study the sedimentary facies of reservoir in Southern Linjiang Region Fuyu in detail.The study suggests that the sedimentary facies of Fuyu reservoir consists of meandering river and shallow water delta;enrichment of sand body is mainly in the northwest and southeast of the study area and sedimentary mudstone is in the central area.
