Abstract: Horizon-oriented impedance attribute can describe the seismic data quantitatively, which contains more than one peak and trough in the same time window. If all the peaks and troughs reflect event of the seam roof lithology can be directly picked up, quantitative attribute can be extracted appropriately, if not, the horizon-oriented attribute would be the best choice. According to the variational lithology of coal seam roof, horizon-oriented attribute should be better to predict the trends. Based on impedance inversion data, combined continuous seismic data and high resolution well logging data together, the paper obtained wave impedance data volume, and abstracted horizon slice to predict the lithology of coal seam roof.
