Abstract As the degree of exploration and development in tight sandstone lithologic petroleum reservoir increases, meandering river-shallow water delta sandstones has become one of the main target areas for current exploration and development activities. The Cretaceous Fuyu oil layer in Shuangcheng block provides an interesting example to study high-resolution sequence stratigraphy in detail. Based on a combination of cores,well logging and seismic data,the boundaries of medium-term and long-term base-level controlled stratigraphic cycles were identified. Fuyu oil layer was divided into two long-term base-level cycles and seven medium-term base-level cycles. Furthermore,the development and characteristics of sedimentary facies and sand-bodies of meandering river-shallow river delta in high-resolution sequence framework were further investigated. The results show that when the long-term base-level showed a trend of rising followed by falling from MSC1 to MSC7,sedimentary facies switched from delta plain,meandering river,delta plain to delta front. The lithology,sedimentary structures,multi-cycles and scales of channel sand-bodies changed accordingly. At the same time,the main types of channel sand-bodies changed from distributary channel,meandering river,distributary channel to subaqueous distributary channel vertically. Sand-bodies were dirtributed as ribbons,and the ratio between sandstone and strata thickness reduced gradually from the southwest source direction to northeast. From MSC4 to MSC5 period,high-quality reservoir sand-bodies were most developed. Under the background of depression lake basin with stable tectonic activities,the variation of lake level is considered the main control on the developent and characteristics of reservoir sand-bodies.
