Quantitative analysis of multiple reflected refraction of land

Key words:  multiple reflected refraction  kinematic  dynamic  eigenvector filter

Abstract:

Multiple reflected refractions are prevailing at uplift of basin, southern mountain carbonate area and piedmont tectonic belt of the west region.The characteristics of multiple reflected refraction including the kinematic and dynamic characteristics were discussed by the related formula derivations. Subsequently, the effects of such interference on amplitude compensation and deconvolution in the seismic data processing flow were also studied. Eigenvector filter multiple attenuation method was used for the attenuation of such noise. The seismic data processing results show that eigenvector filter multiple attenuation method is suitable for the attenuation of such noise and the seismic data after attenuation make imaging profiles of the structure more clear.
