THE CENOZOIC STRATIGRAPHY IN DEEPWATER AREA OF SOUTHERN QIONGDONGNAN BASIN

WU Bing-wei;Exploration and Development Research Institute,PetroChina Liaohe Oilfield Company;  
The geology of the deepwater area of the southern Qiongdongnan Basin is poorly studied.In recent years,seismic exploration has helped revealed the basis geological structures in this area.In order to better understand the Cenozoic stratigraphy of the deepwater southern Qiongdongnan Basin,the author carried out a sequence stratigraphic study integrating new seismic data and regional geological data.Cenozoic strata in the deepwater southern Qiongdongnan Basin can be divided into 2tectonic sequences and 8sequences.From the Paleogene to the Quaternary,this area experienced fluvial-lacustrine facies,transitional facies,neritic and bathyal abyssal facies.Cenozoic strata are well developed in this area,with a maximum thickness of about 10000 mand an area coverage of about 9000km2.These strata host two sets of sourcereservoir-caprock assemblage and have potential for petroleum exploration.
