摘要：

The complex sedimentary characteristics and internal structure of the tidal-controlled estuary dam are still unclear. By means of establishment of an ideal tidal-controlled estuary model, using sedimentary dynamics numerical simulation method, quantitative simulation of sedimentation of tidal-controlled estuary dam and internal interlayer was carried out under different flow and tidal energy conditions. The results show that under ideal conditions, large tidal range and medium flow are conducive to large-scale development of tidal-controlled estuary bars. In the analysis of tidal energy factors, the length-to-width ratio of the tidal-controlled estuary dam is 2-15, the length of the interlayer is concentrated at 8 km, and the thickness of the interlayer is 0.1-0.2 m. In the analysis of flow factors, the length-to-width ratio of the tidal-controlled estuary dam body is 1.5-9.0, the interlayer length is 1-2 km, and the interlayer thickness is 0.1-0.2 m. Simulation results show that the coupled action of the river and tide control the formation and distribution of the bar, but the effect of the tide is more remarkable. Numerical simulation of the sedimentary process of tidal-controlled estuaries based on sedimentary dynamics has been verified by well seismic data, which will provide new ideas for the sedimentary evolution of tidal-controlled estuaries and will guide the exploration and development of oil-bearing reservoirs in the tidal-controlled estuary. © 2021, Editorial Department of Earth Science.
