Study of Sedimentary Facies Using Seismic Attribute Assistance——By Taking Fuyu Reservoir in Southern Linjiang Region of Songliao Basin for Example

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.
