| 摘 要： | 提出了一种随着速度比与转换点深度的变化而动态抽道的转换波速度分析方法,实现了扫描叠加速度、转换点深度与共转换点道集的一一对应,是一种真正意义上的共转换点无迭代速度分析技术,理论模型试算与实际地震资料处理都证明了此方法的正确性与有效性.

| Abstract: | Each sample in a seismic trace has its unique converted point location,which implies that the converted wave velocity analysis can not be done by using fixed seismic gather,and that the common conversion point(CCP) gathers should be changed accordingly when the velocity ratio and conversion point depth are changed.In this paper the authors present a method of non-iterative converted wave stacking velocity analysis using true CCP gathers,which introduces a dynamic trace gathering technique that takes both depth and scanning velocity ratio variations into account.The processing result of seismogram and real multi-component seismic data show that the method is practical and effective. |
