摘要
Sedimentary facies of Member 3 of Shahejie Formation in Banqiao Depression was studied through an analysis of abundant data of core, wireline logging and test analysis, showing that nearshore subaqueous fan was dominantly formed in deep water by turbidity flow and characteristics such as lithology, sedimentary structure, logs, paleo-biology fossil, sedimentary sequence, sedimentary assemblage were summarized to identify the several important and similar sedimentary facies. These methods can be applied to the study of sedimentary facies in analogous fault trough lake basin.
