- W2313535330 abstract "The purpose of seismic migration imaging is to obtain reflection coefficient model. From the perspective of least-square migration which is based on inversion, the results of the conventional migration imaging are consistent with the results that reflection coefficient filtered by Hessian operator. Because of the filtering effect of the Hessian operator, the resolution of the reflection coefficient estimated by conventional migration imaging is usually lower than real reflection coefficient. So the study of Hessian operator's characteristics can help us analyze seismic imaging resolution on the perspective of inversion. This paper studies the main influencing factors of the Hessian operator: seismic frequency band, velocity distribution and geometry, and emphatically analyzes the different geometry's influence on imaging resolution. Then we obtain some conclusions which influence seismic imaging resolution." @default.
