In view of the challenge of insufficient understanding of the flow mechanism of Jiyang Shale Oil in continental fault-depression basins，starting from the perspective of the generalized Darcy’s law，this paper demonstrated the dynamic evolution patterns of the“five fields”comprising the porosity field，permeability field，saturation field，pressure field，and in-situ stress field. In the Jiyang Shale Oil Reservoir，the dynamic coupling of these five fields governs the development of pores and fractures，the occurrence of fluids，and the mechanisms of fluid flow. This coupling ultimately determines the effectiveness of reservoir stimulation and the potential for productivity. Clarifying this coupling mechanism is therefore a fundamental prerequisite for achieving efficient development of shale oil resources. Building upon the spatiotemporal evolution mechanisms of the“five fields”，the paper refined the tri-zone flow model（easily flowing zone，slowly flowing zone，and stagnant zone）. For individual wells，the distribution characteristics of the“five fields”within each zone，their dominant flow mechanisms，and their differential contributions to oil production were clarified. Focusing on the spatial configuration of these three zones between wells，the paper proposed three well-group flow patterns：isolated，competitive，and beneficially interfered types. The technical trend is identified as creating beneficially interfered tri-zone flow through the synergistic adaptation of well patterns to artificial fracture networks combined with balanced fracturing stimulation. On this basis，two key research directions were put forward，namely the fine characterization of the properties of the three zones and the accurate representation of the flow laws of the three zones，which provide theoretical and technical support for the large-scale and economic development of Jiyang Shale Oil.
