平面SH简谐波在粘性流体层上的反射与透射

REFLECTION AND TRANSMISSION OF SIMPLE HARMONIC PLANE SH WAVE ON A VISCOUS FLVID LAYER

本文把胶结极差的含油气砂岩看成粘性或粘弹性流体,建立弹性固体中粘性(或粘弹性)流体夹层模型,求出了平面SH简谐波在流体层上的反射系数与透射系数,它们是与频率有关的函数.

In this paper, the roughly-cemented oil and gas-bearing sandstone is regarded as a viscous or viscoelastic fluid. A model of viscous (or vis-coelastic)fluid layer intercalated with elastic solids is set up. The reflection and transmission coefficients for simple harmonic plane SH wave on the fluid layer are determined. They are categorized to the function of frequency dependence,
