Application of transient electromagnetic method to detect near surface loess layer in Western China

摘要：

　　The topography of the foreland thrust zone in western China is complicated.In those areas, the mountains are steep and the loess layer is thick, which cause the quality of seismic data in these areas is poor.With continuous research in recent years, the quality of seismic data has been improved to some extent.However, it is still difficult to identify the structural traps and build accurate velocity model.It has received a better exploration results on the recognition of loess characteristics and distribution with transient electromagnetic method in the foreland thrust zone.In this paper, the achievement of detecting near surface loess layer in western China using transient electromagnetic exploration is shown.It can be combined with micro-logging to provide the basis for building shallow velocity model for the static correction of the seismic data.
