%X The paper introduces detailed principle of ellipse evolving Common Reflection Point (CRP) stack in the homogeneous media, and introduces two parameters (ratio of up-going wave velocity to down-going wave velocity and average velocity) for heterogeneous media. It reasons rigorously out that evaluated velocity is the real CRP stack velocity with practical geological meaning. The theoretical model computing and seismic data processing confirm that we can use ellipse evolving CRP stack to work out accurate CRP stack velocity and correct zero-offset section of complex geology section. And the effect of imaging is markedly superior to that of conventional Common Midpoint (CMP) method.
