In this paper, seismic inversion of elastic parameters in horizontally layered VTI ( transverse isotropy media with vertical symmetry axis) is well studied, on the basis of seismic wave kinematics theories in transverse isotropic media with vertical symmetry axis. 根据地震波在具有垂直对称轴的横向各向同性(VTI)介质中的运动学特征,应用传播时间反演方法,进行了水平层状VTI介质的地层弹性参数反演方法研究。
