| 摘 要： | 近年来国际上关于各向异性的研究文章发表较多，也报道了一些成功的应用实例。本文通过国内一块三维资料的处理与解释，发现VTI各向异性问题对实际地震成像存在较大的影响。本文基于Alkhalifah(1997)提出的VTI各向异性介质的成像理论，研究了如何求取P波反射资料的各向异性速度和叠加成像问题。出于完整性的考虑，文中对各向异性研究的发展过程，以及本次处理涉及的基本理论做了简要的介绍。

| Abstract: | There are many papers about anisotropy published abroad in recent years and also successful applied cases to be published.Through processing and interpretation of 3 D data at home,the paper discovered that VTI anisotropy has a big impact on real seismic imaging.Based on imaging theory of VTI anisotropic media proposed by Alkhalifah(1997),the paper studied how to calculate the anisotropic velocity of P wave data and stack for imaging.Considering the completeness,the paper briefly introduced the developing process of anisotropic research and the basic theory related to used methods of this processing. |
