瓦尔顿(1970—1971)讨论的三维地震系统,探索了用地震法研究从地表到深反射面的地层柱状。其资料解释直接根据测出的信号纲格上的显示进行。本文导出了预计的三维系统显示图形的多种表达式,反回到检波器的能量是由平面反射、断层绕射或点散射、任意形状反射面的反射、平面折射和反射—折射、以及直达的或表面的波所组成。举出了典型的例子。推导限于几何地震学而不涉及振幅的变化。从地表到反射面、折射面和绕射源的平均速度是假设的。
The three-dimensional seismic system discussed by Walton (1970-1971) explored the use of seismic methods to study the stratigraphic columnar shape from the surface to the deep reflecting surface. The data interpretation directly based on the measured signal on the grid display. In this paper, we derive a variety of expressions for the predicted three-dimensional system display pattern. The energy back to the detector is determined by plane reflection, fault diffraction or spot scattering, reflections of arbitrary shape reflecting surface, plane refraction and refiection-refraction, Or surface waves. Give a typical example. Derivation is limited to geometry seismology and does not involve changes in amplitude. The average velocity from the surface to the reflecting surface, the refracting surface and the diffraction source is assumed.
