  • In Songnan 3D area in the northern margin of the southern uplift of the Qiongdongnan Basin,seismic sedimentology has been applied in the studies of platform edge reef based on recent 3D seismic data with high resolution.The style of active generation unit of reef is controlled by the fluctuation of sea level,and based on which a reef generation model has been established.Seismic attribute has been applied to describe the distribution of sedimentary microfacies of platform edge reef.Combined with reservoir porosity inversion restricted by velocity model,the physical property of reservoir can be predicted.Platform edge reef growing in the study area is characterized by complex border.Amplitude features among different layers reveal the spatial distribution of growth unit of platform edge reef in small and equal period.Abnormal low velocity zones in porosity study are potential targets for exploration.This research may provide new ways for reef-hydrocarbon reservoir exploration in the Qiongdongnan Basin.
