论文摘要
我们引入了对各向异性声学建模的时域波场重建反演的概括。近年来,Wavefield重建反演的能力已得到了大量研究。原始方法是通过声学各向同性物理学在频域中制定的。但是,频域建模需要复杂的迭代求解器,这些迭代求解器难以扩展到工业大小的问题和更现实的物理假设,例如本研究的对象,例如倾斜的横向各向同性。此处介绍的工作基于最近提出的波场重建反演的双重公式,该公式允许适合大尺度和更准确的物理学的时域传播器。
We introduce a generalization of time-domain wavefield reconstruction inversion to anisotropic acoustic modeling. Wavefield reconstruction inversion has been extensively researched in recent years for its ability to mitigate cycle skipping. The original method was formulated in the frequency domain with acoustic isotropic physics. However, frequency-domain modeling requires sophisticated iterative solvers that are difficult to scale to industrial-size problems and more realistic physical assumptions, such as tilted transverse isotropy, object of this study. The work presented here is based on a recently proposed dual formulation of wavefield reconstruction inversion, which allows time-domain propagator that are suitable to both large scales and more accurate physics.
