摘要
Ray tracing is an important tools of seismic data processing,and seismic traveltime calculation is the key problem of ray theory.Plane wave approximation algorithm has low accuracy,and weak adaptive of medium velocity,so in this paper,it makes improvement about ray tracing algorithm based on spherical wave approximation algorithm.The data simulation results indicate that this algorithm is right,and able to handle speed distortion interface efficiently,improving calculation efficiency without producing an effect on calculation accuracy.
