Abstract: The thermal evolution of porosity and permeability, as well as the physical properties, of Baishihu and Shitoumei mining areas oil-rich coal in the Santanghu Basin exhibit significant differences, directly affecting the setting of pyrolysis process parameters for coal samples. Baishihu coal is characterized by high vitrinite content, high volatile matter, and high tar yield. During thermal evolution, it exhibits a “stepped” change, with porosity plummeting to 8.0% and permeability dropping from 478.5 mD to 77.6 mD during the peak oil generation period at 300-400 ℃, resulting in a trough in thermal conductivity （0.275 W/（m·K）） and exhibiting a thermoplastic plugging effect. Shitoumei coal, on the other hand, is characterized by medium-high vitrinite content, high inertinite content, and high fixed carbon. Its porosity and permeability parameters increase monotonically with temperature, reaching 27.71% porosity and 537.6 mD permeability at 600 ℃, with a steady increase in thermal conductivity. Its reactivity is consistently superior to that of Baishihu coal. Microscopic analysis indicates that Baishihu coal seepage relies on fractures and pyrolysis pores, while Shitoumei coal relies on primary cell cavities to form a three-dimensional network. Therefore, it is proposed that Baishihu should be used for “oil extraction followed by semi-coke gasification” and Shitoumei is suitable for a cascade utilization path as gasification feedstock.
