共成像点道集(CIG)叠加方法研究

In order to probe the relationships between wave equation offset domain common image gathers (ODCIGs)/angle domain common image gathers (ADCIGs) with migration velocity, we quantitatively derive the changes of ODCIGs and ADCIGs along with migration velocity on the assumption of uniform velocity medium with a horizontal reflector.

为了得到波动方程偏移距域共成像点道集(ODCIGs)和角度域共成像点道集(ADCIGs)与偏移速度的关系,在匀速单层水平反射情况下,对ODCIGs和ADCIGs随偏移速度的变化进行了定量的推导,得到偏移速度偏小时ODCIGs与半偏移距成双曲关系,反之成椭圆关系;结合深度聚焦分析,得到偏移速度偏大时,ADCIGs中视入射角大于真入射角,反之,小于真入射角;在速度偏小时,ADCIGs上剩余时差(RMO)与视入射角的正切值成椭圆关系,反之成双曲关系。
