Abstract Calculating travel time of seismic wave is an important part of the fields of seismology and seismic exploration. It is widely used for prestack migration, velocity analysis, seismic tomography, earthquake location, and so on. Analysis of the examples and effects of ray paths and travel times by applying the Ronge-Kutta ray tracing method, and comparing the results of the Ronge-Kutta ray tracing simulations and the effect of hodograph by eikonal equation calculated in several typical geological models of seismic exploration. Simulation results verify the stability of the eikonal equation finite-difference method in the calculation of travel times and the implementation of Ronge-Kutta ray tracing method. The study also shows that the Ronge-Kutta ray tracing method in complex structure region seismic ray paths and travel times calculation gets better simulation results.
