Numerical simulation analysis of interwell elastic wave field scattering characteristics
Online published: 2011-06-20
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 the interwell seismic wave field, and the difference between its size and the wavelength of the P-wave and Swave will raise complexwave field characteristics, such as multi-scattering and reflection wave. Compared with P-wave, the S-wave with smaller wave length ismore easily to raise the scattering wave field.
