摘要
Based on the geology,geophysics and predecessors studies and applying sedimentary principles and methods,this article makes a detailed analysis of the feature of sedimentary faces in Liaodong Bay’s second member of Paleogene Dongying Formation.It is indicated that although the whole second member of Dongying Formation is lake-deltaic depositional system,the difference of the upper and lower parts of second member of Dongying Formation is obvious.The lower part mainly included lake system,while the upper part mainly included delta facies.After taking together the structural feature and development of water systems in this zone,the author draws up the distributing feature of sedimentary faces in both upper and lower parts of second member of Dongying Formation.Finally,this article forecasts that the end of north inclined in low swell of Liaoxi and south-central sub-sag of Liaozhong sag are the most favorable exploration targets.
