Abstract：Under long spread condition, using 3 time-distance curve equations (Routine-hyperbolic curve time-distance equation, and two non-hyperbolic curve time-distance equations which containing high order and anisotropic parameters) to describe the characteristics and accuracies of seismic wave propagation were studied in this paper. The study results show that under long spread condition the high order and anisotropic non-hyperbolic curve velocity analysis method could get accurate stacking velocity and interval velocity, as a result better NMO and stacking results can be achieved. But when the spread is too long, accurate stacking velocity could not be obtained with high order non-hyperbolic curve method, and the anisotropic non-hyperbolic curve has a wider application scope.
