Abstract: A pseudo log inversion method of seismic attribute is discussed.The pseudo log responding coal seam character was inverted from seismic attributes.The method uses log and seismic attributes of well and form a network model via neural network train,then invert seismic attributes of non-well by this model and derive 3D log data.The data is of higher resolution vertically and accurate distribution laterally,and can provide precision distribution character of coal seam by interpretation.
