含高速层地震物理模型的广角地震波场研究

Investigation of WARRP seismic wavefield on physical model with a high velocity layer.

广角地震可以实现对高速屏蔽层下模糊区的地震成像。利用地震物理模拟技术在实验室内再现了野外观测到的复杂地震波场。讨论了地震物理模型设计的比例观测原理,地震模型的设计与建造。通过地震物理模型的分层观测,详细研究了高速屏蔽层下的复杂地震波场。

Wide-angle reflection and refraction seismic has been successfully used to image zones beneath high velocity layer. In this paper, field seismic wavefields were simulated with seismic physical modeling technique. We discussed the scaling observation principles of the construction of seismic physical model, as well as design and building of seismic physical model. The complex seismic wave-field beneath high velocity layer was investigated on layer-stripping observations of seismic physical model.
