Some thoughts on common reflection surface stack in practice

YANG Kai, MA Zai-tian (School of Marine&Earth, Tongji Univerisity, Shanghai 200092, China) A  
Common Reflection Surface (CRS) stack is a special zero-offset imaging method. It is independent of macro-velocity model and full data-driven realization in practice. According to CRS stack theory, not only the high-quality zero-offset section is obtained, also the three useful wavefield attributes are computed to invert macro velocity model, the ideality post-stack depth migration after CRS stack will outperforms pre-stack depth migration. The above features is inspiring, but they cause problems in practice. The dip decomposing CRS stack was proposed to deal with these problems. In this paper, some thoughts are summarized after practicing the CRS imaging method.
