Abstract The Member 2 of Paleogene Shahejie Formation in Banqiao area of Huanghua Depression developed typical lacustrine beach-bar deposits with three kinds of inter(inner)-layer in sand bodies,i.e., muddy,calcareous and compact silty inter(inner)-layer. The beach-bar sand bodies can be divided into three architecture elements using the reservoir architecture analytical method:Compound bar,single bar,and the inner accretion of single bar. The inter(inner)-layers in the beach-bar reservoir can be subdivided into two hierarchies:Inter-layer between single bars and inner-layer in single bar. There are three genetic mechanisms of inter-layer between single bars:①Fine-grained sediments developed in a region superimposed by two-phase single bars sand bodies caused by base-level change;②Retention mud-gravels drawn by storm activities;③Mud deposit in a low wave energy behind bars. The fine-grained inner-layers in single bar are formed by the attenuation of wave energy,and mainly consists of silty mudstone and argillaceous siltstone. Further research is to dissect architecture inner single bar through well-log facies recognition and modern beach-bar prototype geological models in Qinghai Lake and Daihai Lake. It is found that the muddy inner-layers in single bar with thickness about 0.1～1m are nearly horizontal close lakeshore and inclines in low angle towards the center of the lake,with 2°～5° dip angle. Each hierarchy and genetic inter(inner)-layer is found in a certain region in a single bar sand body. The relative position and distribution pattern of each inter(inner)-layer can not only reflects the order of deposition in a single bar,but also be used to predict the scale and morphology of beach-bar. The inter(inner)-layers can lead to the diversity of oil-bearing properties, therefore it is important to reveal the distribution of inter(inner)-layers in beach-bar reservoirs, which is the key to raise oil and gas recovery ratio.
