Determination of Accoustic Impedance from Seismic Reflection Data
초록
Accoustic impedances of subsurface layers are determined from the amplitudes of reflections from the layers. Densities of the layers can also be calculated from the accoustic impedances in case where velocities are known by velocity analysis of reflection data or any other method. The accoustic impedance is a good information for direct identification of the kind of some subsurface material like coal or oil.
