摘　　要：通过井震联合反演,研究煤系地层的横向变化,预测煤层的顶、底板岩性;从地震属性中优选出波阻抗属性、振幅属性、频率属性对小构造和煤层顶、底板岩性进行分析.得出联合测井信息,综合利用地震多属性分析可以从常规几何构造的解释向物性结构的解释过渡,提高了煤田勘探的解释精度,减少了解释的多解性.Using joint inversion of logging and seismic data, the transverse change of coal measure was studied and the lithologies of coal seam roof and bottom was predicted. Wave impedance, amplitude and frequency attributes were applied to the interpretation of seismic data, analyzing the small structures and the lithologies of coal seam roof and bottom. The result indicates that comprehensive utilization of seismic multi-attribute analysis and logging data can convert conventional geometric structural interpretation to property interpretation, improve the accuracy of interpretion in coal exploration and reduce the multiplicity of lithology prediction.
