在各向异性介质中,短排列叠加速度一般与均方根垂向速度不同。即使已记录了P波和S波,在短排列共中心点道集上进行双曲时差分析时,由于存在各向异性影响,我们仍难以恢复垂向速度(或反射层深度)。因此,我们检验了用长排列(非双曲)反射时差反演求取具有垂直对称轴的横向各向同性介质参数的可行性。一个可能的解是恢复取P波和S波t~2—x~2曲 In anisotropic media, the short stack rate is generally different from the root mean square vertical speed. Even if P-wave and S-wave have been recorded, it is still difficult to recover the vertical velocities (or reflector depths) due to anisotropy when performing hyperbolic time-difference analysis on short-aligned concentric point gathers. Therefore, we test the feasibility of determining the transversely isotropic media parameters with a vertical axis of symmetry using long-run (non-hyperbolic) reflectance time-difference inversion. A possible solution is to recover the P wave and S wave t ~ 2-x ~ 2 song
