摘要
利用时差特征对P-SV转换波的参数进行了估计。基于P-SV转换波双平方根时距关系,根据扫描得到的纵波速度、纵横波速度比或转换横波速度的结果,进行P-SV转换波时差估计。模型和实际资料表明了方法的有效性和准确性。
This paper adopts the characteristics of kinematics to estimate the parameters for P-SV converted wave.Based on the converted wave non-hyperbolic time-distance curve equation,by scanning the P-wave velocity at common middle point(CMP),the ratio of P-and S-wave velocity or the converted S-wave velocity at common converted point(CCP),moveout are estimated.Synthetic and real data results showed the validity and correctness of the method.
