Abstract:
The zero-offset common reflection surface(ZO CRS)stack, which is a new stacking method to enhance the quality of engineering seismic data, was investigated. The conventional methods of zero-offset(ZO)section simulation need precise macro-velocity model and can not provide the best illumination for the reflecting interface in the subsurface. The ZO CRS stack is an entirely data-oriented seismic reflection imaging approach of ZO section simulation in a macro-velocity model independent way, and this method can provide the best illumination for the reflecting interface in the subsurface and enhance the simulated ZO section. Because the ZO CRS stack was not applied in Chinese engineering seismic prospecting widely, the theory and implementation of ZO CRS stack were introduced in detail. The ZO CRS stack was applied to a synthetic data set of fault model and a real data set from a two-dimensional seismic line acquired nearby a certain highway, respectively. Application of ZO CRS stack on synthetic examples and engineering seismic records showed that the technique can improve the stacked section by increasing the signal-to-noise ratio and enhancing the consistence of reflection event, and the results reveal that the ZO CRS stack method is a promising engineering seismic imaging method of ZO section simulation.
