摘　　要：为了研究深部煤储层孔隙结构特征及其分形规律,选取了河北大城地区埋深介于1 000～1 400 m的煤层作为研究对象,通过压汞测试揭示了研究区孔隙结构特征.利用分形维数研究孔隙分形规律,表明深部煤储层孔隙分形维数介于2.241 8～2.424 6,满足分形维数要求,孔隙存在分形特征且为中等复杂结构.Selects the coal seam which the buried depth is between 1 000-1 400 m as research object to study the characteristics of pore structure and its fractal laws in deep coal reservoir of Dacheng area, Hebei province. Through analysis Mercury injection experiment data. Study on fractal laws by fractal dimension of pore displays that the pore fractal dimension of deep reservoir ranges from 2.241 8 to 2.424 6,which meets the standard of fractal dimension,showing the pore has fractal characteristics and secondary complex structure.
