In order to improve the precision of non-hyperbolic anisotropic velocity analysis and adapt the velocity analysis to far offset or other complex circumstances, the authors confirm the reliability of non-hyperbolic velocity analysis by summarizing the basic steps of velocity parameters estimation of non-hyperbola in layered media and using numerical simulation and resemblable analysis, and the error between inversion result and theoretical value is about 1%. The error analysis of anisotropic parameterη indicates it is sensitive to the error, and the error between inversion result and theoretical value is as high as 12.87% , so it is best to pick η directly to increase the precision of velocity analysis.
