摘要
By analyzing the analytical data of the coring well in the Well Block-9(emphasize on the Well Block-9-6 and the Well Block-9-9),the subzone has been separated and correlated in Badaowan Formation,and also the Deposition features has been studied,based on the sufficient data from well logging,drilling and earthquake.Through these studies,it is pointed out that the type of Microfacies-Lithofacies in this area belongs to the Braided-river Delta,and the relationship between Sedimentary-Microfacies Characteristics and reservoir is analyzed.
