摘　　要：通过对阳泉煤业集团创日泊里煤业有限公司首采区三维地震数据体及其解释成果结合测井资料进行多井约束下的波阻抗反演,并通过层位标定确定煤层所对应的波阻抗层,然后提取该波阻抗层的厚度并与钻孔见煤点处的煤层厚度进行拟合匹配,最终得到三维地震测区的煤层厚度分布规律。Through acoustic impedance inversion of the confined multi borehole geophysical logging data and seismic data and its interpretation of 3D seismic survey of the chuangriboli coal mine of Yangquan coal group and through the marker of the coal seam and its impedance the thickness of the coal seam in the boreholes and the thickness of the impedance marker were fitted and regressed, and finally the coal seam thickness of the 3D seismic area were mapped.
