VTI medium ray tracing method and device, electronic equipment and medium

The invention discloses a VTI medium ray tracing method and device, electronic equipment and a medium. The method comprises the following steps: aiming at a VTI medium, solving a Christoffel equation through a characteristic value method according to a Thomsen parameter, and obtaining a longitudinal wave eikonal equation; solving a path function equation of longitudinal waves to obtain a kinematics ray tracing equation of the VTI medium; and solving a kinematic ray tracing equation through a Runge-Kutta method to realize ray tracing of the VTI medium. VTI medium ray tracing is performed through the Thomsen parameter of the VTI medium obtained in actual seismic velocity modeling, so that travel time required by depth domain migration imaging of the underground medium is established, and the depth domain migration imaging efficiency and effect of the VTI medium can be improved. 本申请公开了一种VTI介质射线追踪方法、装置、电子设备及介质。该方法可以包括：针对VTI介质，根据Thomsen参数通过特征值法求解Christoffel方程，获得纵波的程函方程；求解纵波的程函方程，获得VTI介质的运动学射线追踪方程；通过龙格-库塔法求解运动学射线追踪
