摘要

The location of conversion point for P-SV converted waves is important for binning and gathering traces. There have been some techniques for the calculation of P-SV conversion point in the case of a dipping bed or horizontal layered medium. A method is proposed to estimate the P-SV conversion point in the case of layered medium with multi-dipping interfaces. The location of P-SV conversion point can be estimated by searching the optimal incident angle and reflection angle depending on Snell’s law. At the same time, the method can also estimate the ray path of P-SV waves.
