thin bed
4.Successful experience is stated on reduction of ore-dilution in some uranium mine where a moderate dip and thin-bed deposit of sedimetary sandstone type has been mining.
6.AVO technique has unique advantage in lateral prediction of hydrocarbon reservoir. However,low signal-to-noise ratio and thin-bed effect make very difficult the application of AVO technique in this field.
7.Apparent absorption coefficient and pseudo absorption coefficient are adopted so as to remove the influence which the waveform distortion dueto thin bed tuning brings to absorption coefficient extraction. The final instantaneous equivalent absorption coefficient,a true absorption coefficient which reflects real absorptive character of a seismic medium,can be obtained by subtracting the pseudo absorption coefficient(inversely calculated using maximum entropy)from the apparent absorption coefficient we have calculated.
