摘    要:为了更精确预测煤层厚度变化,分析了波阻抗反演与煤厚的相关性,对测井资料和反演后的合成地震波振幅进行线性回归,建立了原生煤的正演模型.将该模型应用到非井点的地震属性上,利用同位协同克里金方法实现了对淮北桃园矿区煤层厚度的预测,结果与已知钻孔探测资料十分吻合,证明了利用地震振幅预测煤厚以及分类正演模型是可行的.

关 键 词:波阻抗反演  煤层厚度  合成地震波振幅  同位协同克里金

Abstract:To predict the thickness change of the coal seam more accurately,the correlation of impedance inversion and coal thickness were analyzed.Through linear regression with log data and inverted synthetic seismic amplitude,the original coal forward model was established,which was applied in predicting the thickness of coal seams with collocated kriging in Taoyuan coal mining area,Huaibei.The prediction error of seam thickness was close to zero at well location.The result showed that classified forward model and ...
Keywords:impedance inversion  thickness of coal seam  synthetic seismic amplitude  collocated kriging
