Abstract: The pore structure of coal seams has a significant influence on the adsorption and diffusion of coalbedmethane. By means of gas adsorption，nuclear magnetic resonance and scanning electron microscopy，a multiscale and multi-parameter joint characterization of coal seam pore structure of Jurassic Yan’an Formation in Shenmu area of Ordos Basin was carried out to clarify the law of desorption，diffusion and seepage of coalbed methane. The results show that：（1）The coal seams of Yan’an Formation in Shenmu area have average porosity and permeability of 6.89% and 4.82 mD respectively，which belong to typical ultralow permeability coal seams， mainly developing calcite，clay minerals and amorphous components，of which the average mass fraction is 54.8%，35.7% and 15.0% respectively.（2）The main reservoir spaces of coal seams in the study area are narrow‐slit shaped and ink bottle shaped，including stomata，interchip pores，cell pores，mold pores and a few microcracks. The pores are dominated by mesoporous pores with pore size of 2-50 nm，followed by macropores，with the least amount of micropores. However，micropores are the main contributors to the specific surface area and pore volume of pores，indicating that coalbed methane is mainly adsorbed in micropores.（3）The pore throat size of coal seams in the study area varies in nano-and micron-level，the contribution to permeability mainly comes from submicron to micro pore throats，indicating that the pore connectivity in this range is good. The movable fluid saturation of coal samples is 38.72%-65.06%，the mercury removal efficiency is 0.84%-44.30%，the homogenization coefficient is 1.86-10.95，and the contribution of pore throat radius to permeability at different depths were significantly different，indicating strong heterogeneity in this area.

Key words: nuclear magnetic resonance, gas adsorption, heterogeneity, micropore, pore structure, coal seam, Yan’an Formation, Jurassic, Ordos Basin
