摘要
地震勘探物理模型实验中,采用页面物理模型模拟实验技术,可以降低物理模型的制作成本,缩短实验周期。采取加工与观测同步进行的方法,可以分解复杂构造模型的地震波场,有利于研究各类震波在模型中的传播问题。笔者介绍了页面模型的制作和观测技术,讨论了页面模型上波的分布特点,描述了典型构造模型的地震波场。可以发现,页面物理模型的制作和观测简单,制作周期短,成本低;在得到的地震波场图上,各类震波的运动特征明显而清晰;它不仅可以模拟各种简单的地质构造,在开展复杂构造的三维地震勘探物理模型实验时,有利于各类震波的识别与分析。
The thin-plate modeling technique can reduce production cost and shorten production circle in physical experiments of seismic exploration.By simultaneous performance of the manufacture and observation,this processing and observation method can decompose seismic wave fields and help us know the propagations of various types of seismic waves in complicated media.This paper reports the manufacture and observation technique of the thin-plate model,discusses the characteristics of wave distribution in the thin-plate model,and describes the seismic wave fields of typical structure models.It is found that the thin-plate physical model has the advantages of simple manufacture and observation,short manufacture cycle and low cost;in addition,the movement characteristics of various seismic waves are obvious and distinct in the obtained seismic wave field map.It can not only simulate various simple geological structures but also help recognize and analyze different kinds of seismic waves during the 3D seismic exploration physical modeling of complex structures.
