摘要
In Songnan 3D area in the northern margin of the southern uplift of the Qiongdongnan Basin,the seismic sedimentology has been applied in the studies of platform edge reef based on recent 3D seismic data with high resolution.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.
