| 摘 要： | DMO方法能够使来自不同倾斜界面的反射波同时得到有效叠加。根据DMO处理后的CMP道集,可以得到准确的叠加速度。本文在分析Dave Hale和Houston大学DMO算法的基础上,采用FFT算法实现了一种精确、快速的DMO算法。理论模型及实际资料的处理结果表明,这是一种实用而准确的DMO算法。

| Abstract: | DMO method can cause satisfactory stack result of the reflection waves which come from different dip reflectors. Accurate stack vetocities can be obtained from CMP gathers which have undergone DMO processing. An accurate fast DMO algorithm is developed by taking FFT algorithm and the advantages of Dave Hale's DMO algorithm and Houston University's DMO algorithm.The processing results of synthetic and real data prove this DMO algorithm feasible and accurate. |
