The analysis of influencing factors and time- space evolution of salt tectonics in passive continental margin basins is highly regarded by the scientific community. Due to the abundant oil and gas resources in passive continental margin basins, the quality of seismic data has continuously improved. The interpretation results of high- precision seismic data show that the topography under the salt layer of passive continental margin basins often has large undulation characteristics. However, previous studies on the influence of basement tectonic morphology on the formation of salt tectonics has not reached a consensus, and in- depth research and discussion are still needed. Therefore, based on the previous research, this paper adopts the physical simulation method. Through the description and comparative analysis of the plane and section tectonic of the two groups of models, the research on the control effect of the continental rise slope on the salt rock deformation was carried out. The simulation results show that compared with the flat subsalt terrain, the existence of continental rise slope can enhance the flow capacity of salt rock, and promote the formation of more structural styles and larger- scale deformation of salt tectonics at the same time. The research in this paper can further enrich the theoretical understanding of salt tectonic deformation in passive continental margin basins and clarify the temporal and spatial evolution of salt tectonics and oil- gas.
