| 摘 要： | 地震波正演数值模拟是实现井间弹性波波场分析的重要手段。文中采用弹性波波场分离数值模拟技术对层状含孔洞的速度模型进行了井间波场观测和波场特征分析，通过改变孔洞尺寸及其纵横波速度来研究井间地震波波场的散射特征。数值模拟结果表明，孔洞的存在增加了井间地震波波场的复杂性，且其尺寸与纵横波波长之间的差异将产生诸如以多次散射和反射等为主的复杂波场特征；横波波长较短，比纵波更易引起波场散射。

| Abstract: | Forward numerical simulation is the key mean for analysis of interwell seismic wave field.The elastic wave field separation numerical simulation technology is used to carry out interwell wave field observation and its characteristic analysis on layered medium model with a cavity,and to study the scattering characteristics of interwell seismic wave field by changing the cavity size and compressional velocity and shear velocity.The numerical simulation result shows that the cavity increases the complexity of ... |
