1复杂介质下保真振幅Kirchhoff深度偏移显示文摘本文详细讨论地下复杂介质地震成像问题.当速度模型含有强横向变化时,射线场会折叠形成多次走时,在这种情况下,文中证明在保真振幅叠前深度偏移时,应当考虑所有的到时才能得到定量的像.通过实例证明,在多次走时情况下,常规的共炮集、共检波器集都存在强的假像;由此提出共角度偏移的概念.最后,在多次走时下,讨论多次偏移算子(走时、相移、振幅等)的高效重构,给出了三维叠前深度偏移的快速算法.徐升 Gilles Lambaré 2006地球物理学报2006,49,5:44

9相空间中的保真振幅偏移显示文摘在三维地震资料叠前偏移中,平面波偏移的成像效果可以等价于共炮点偏移,但计算效率却能成倍提高。此外,保真振幅偏移可以得到地下反射层的相对强度,获得品质更好的地下结构图像,为储层分析提供定量信息。基于这种考虑,针对平面波的保真振幅偏移进行了系统的研究。引人Maslov理论,利用τ-ρ变换将数据从空间(s,r,t)分别变换到(P^s,r,τ)和(s,p^r,τ)及(p^s,p^r,τ)空间中,并将其结合到Born反演中,推导出了相空间偏移算子振幅的高频渐近解。基于Marmousi复杂地质模型的模拟计算结果表明,平面波的保真振幅偏移在合理的计算量条件下可以得到高品质的地下结构图像。徐升 Gilles Lambaré 2009石油物探2009,48,1:1
