One new imaging method for near surface seismic survey and application

摘要

The criterion of geologic structure characters is small, decency is serious and anisotropy is prolific in near surface. So the seismic record is very complex, simultaneously the frequency band is wide, particularly the high frequency effective information is prominent, and the noise is serious, the energy reflection event is weak and non-reflection ingredient scattering wave is prolific. All these hindrance distinguish and trace the effective reflected wave seriously. In this case, there is one enormous challenge with the technical of multifold horizontal stacking reflected wave survey and the imagination which based on the traditional level lamellar geology model, simultaneously extracting the geology information has been influenced seriously. In view of the particularity and complexity of the typical geology fault localization in near surface, the paper applies seismic scattering wave imaging technical to processing one near surface geology disaster target area with seismic scattering wave, and has made a good progress.
