AN OUTPUT IMAGING SCHEME OF COMMON REFLECTION SURFACE STACK

摘要

In seismic literature, Kirchhoff-style imaging methods have been classified as two kinds of schemes: input imaging scheme (IIS) and output imaging scheme (OIS). Among Kirchhoff-style migration-to-zero-offset (MZO) methods, common reflection point (CRP) stack and common reflection surface (CRS) stack are two distinctive methods. Considered from the viewpoint of IIS and OIS, they belong to IIS. In this paper, the CRP stack and the CRS stack are presented as an OIS in constant velocity media. The numerical tests on the synthetic data shows that CRS stack by OIS exactly achieves what the CRS stack method claims to do in a different way. The implementation of the CRS stack by OIS reveals some interesting theoretical aspects of the CRS stack method which will help to understand CRS stack more deeply and promote its potential in application.
