SIZE: 14pt; mso-fareast-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA" lang=EN-US>Based on comprehensive analysis of core descriptions, thin section observation, paleontology, source area and well logs, the characteristics of sedimentary facies and sequence stratigraphy of the 6th oil-bearing member of Yanchang Formation in Shijiawan area, Ordos Basin, were studied in detail. According to the analytic results of source area, sedimentary facies and sequence, combined with single factor analysis and multiple factors synthesis, the rising and falling base-level phases of medium-term sequence cycles were selected as the iso-chronic stratigraphic unit to compile the sequence-based lithofacies and paleogeography maps. It was concluded that paleogeography and sand body distributions were controlled by lake level fluctuation and source area direction.
