长排列条件下三种时距曲线方程精度分析

 本文研究了长排列情况下，三种时距曲线方程（常规双曲线时距曲线方程、包含高阶项和包含各向异性参数的两种非双曲线时距曲线方程）描述地震波旅行时的特点和精度。研究结果表明：在长排列的情况下，高阶、各向异性的非双曲线速度分析方法可以得到精度较高的叠加速度和层速度，进而获得相对较好的动校正结果及叠加效果。当排列长度过大时，高阶非双曲线方法不能得到相对准确的叠加速度，各向异性的非双曲线方法具有更好的适用范围。

Accuracy analysis for 3 time-distance curve equations under long spread condition

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 ...
