Abstract

Summary

The TZ area in western China is a desert topography with huge mobile sand dunes on the surface. The thick and loose sand layer absorbs most of the high-frequency energy of seismic waves, and Q absorption is very strong, which seriously affects the quality of seismic imaging. In general, Q compensation technology is used to solve the high frequency absorption problem in the middle and deep layers. This paper attempts to introduce this technology to compensate for the absorption of near-surface and to develop a feasible treatment plan. The practical application shows that the Q compensation effect is obvious and the method is effective.
