摘要
在各向异性介质中,地震波的传播速度随着波传播方向的不同而存在差异。各向异性的研究对于岩性地震勘探等工作的开展是有一定的理论和实际意义的。 在本文中,作者阐述了各向异性介质波动射线方法的基本原理,并利用波动射线法研究了二维非均匀的各向异性介质中地震波的运动学问题。
Abstract
In anisotropic medium, the seismic velocity varies with its propagation direction. The research for anisotropy is, for a certainty, of great significance both in theory and practice for the development of lithologic seismic survey and the like.In this paper, the fundamental principle of seismic ray-tracing in anisotropy medium was expounded. With the help of ray-tracing, the kinematic problems concerning the seismic wave propagation in 2D heterogeneous anisotropy medium weve studied and examined.
