一个考虑到炮检距的速度反演递推公式

由于实际地震资料是一定炮检距范围内共中心点道集叠加的结果，建立于地震波垂直入射似设基础之上的常规人工合成地震记录与波阻抗反演方法，常导致错误的解释结果，垂直入积压假设不能反映地震波传播的实际情况，通过对Ｚｏｅｐｐｒｉｔｚ方程的合理简化，推导出了一个考虑炮检距变化的反射系数递推公式。经地质模型试算，证明了该公式的正确性。

A p-p recursive reflection formula relative to the offset variety

The practical seismic section is the result, in which the traces with the same center point are performed by stacking, but normally making synthetic seismogram and wave impedance inversion presume that seismic wave transmits down vertically, which usually causes the wrong interpretative conclusion. In order to solve the problem, a recursive reflection formula is put forward,simplifying Zoeppritz equation now. Theory and numerical experiments verify the precision of the formula.
