本文根据欧拉方程对于连续性层状介质进行了方程推导，得出一个波传播的射线路径公式，利用路径公式导出了VSP资料处理中的速度反演公式。射线路径公式和反演公式都很简单。数值模拟结果表明本文所给方法行之有效。
Based on the Euler equations, the equation of the continuous layered media is deduced and a ray propagation path formula is derived. The formula of velocity inversion in VSP data processing is derived by using the path formula. Ray path formulas and inversion formulas are simple. Numerical simulation results show that the method given in this paper is effective.
