The cross - well seismic forward modeling program can be applied to geological model that has different velocities and dips to calculate cross - well seismic synthetics for given sources and receivers by ray tracing the least traveltime or four order differential wave equation 研制的井间地震正演合成记录的程序，可用来对不同速度、不同倾角的地质模型，通过最小旅行时的射线追踪或四阶差分声波波动方程，计算出对于给定震源和给定检波点的井间地震合成记录。
