Abstract

Abstract: The high frequency part of seismic wave propagation in subsurface is easy to be absorbed or attenuated. The study of mechanism of the seismic wave absorption and attenuation is conducted in order to partly compensate the high frequency part that is absorbed and attenuated. In fact, this complex mechanism is hardly to be described or compensated using a simple mathematic model and seismic instrument. However, the compensation is still of significance in improving the inverse resolution of geological structure and lithologic distribution. The absorption and attenuation of seismic wave propagation is not only related to lithology, but also depended on the complicated propagation path with non-vertical self-transmitting and self-receiving. It is concluded that studying the compensation method of seismic wave absorption and attenuation along its propagation path is more precise and closed to the real conditions than available single-trace compensation technique as a conventional or fundamental method.

Key words: viscoelastic medium, seismic wave, absorption, attenuation, resolution, compensation
