Abstract:With the limited geological information in southeast Hainan Basin and by jointly utilizing drilling date in nearby shallow area and the seismic data in deep water area,a 3D isochrone sequence stratigraphic framework for Lingshui Formation in deep water area of southeast Hainan Basin was established.By integrating the regional geology in the basin and the related works done before,fully utilizing the lithology sequence characteristics from the observation of shallow water cores and the seismic progradation reflection characteristics on seismic sections in deep water area,and summarizing study results on sedimentary facies and seismic inversion sand-body prediction,the material source development status of the Lingshi Formation in Paleogene was analyzed in this paper.The study results indicate that the development in shallow area was from the large range material source in Hainan Island,while the development of the Lingshui Formation from the south to the north in deep water was from the large range material source on Yongle Uplift in the south,meantime some small eroded areas exist in local high positions,those eroded areas provide local material source which was radially distributed from high positions to low positions.Based on the material source analysis in this paper the possible distribution areas for the favorable sand-bodies,such as fan delta,beach bar and turbidite fan,were inferred.
