The migration system, as the primary medium linking source rocks and traps, plays a vital role in studying hydrocarbon migration, accumulation, reservoir formation. This study focuses on Late Paleozoic rock (mudstone coal rock) sandstone samples from Ordos Basin. By analyzing permeability, porosity, their ratios under various conditions, this evaluates quality of pathways across different lithologic strata, identifies optimal routes, offers new insights for identifying favorable exploration areas findings indicate that permeability ratio between parallel vertical bedding planes ranges 1 to 4. Post-fracturing, increases by over twofold. On average, is approximately 0.1 × 10⁻3 μm2, while about 0.03 μm2. Key conclusions include without fracture development, porosity outperform those perpendicular planes, with showing better properties than rocks. When fractures are present, along direction highest, followed sandstone, lowest values. These results advance theoretical understanding systems provide significant guidance development.
