波动方程偏移迭加的两种方法我们喜欢将普通地震剖面想象成代表地下的垂直切面,实际上它们不是如此。在构造复杂的地区,一个地震剖面只是所接收到的通过地表的波动场。这些波是由地表引入的地震能量从地下散射源来的回声。 Two Ways to Overlay the Wave Equation Offset We like to think of a normal seismic profile as a vertical slice that represents the ground, but in fact they are not. In a complex area, a seismic profile is simply the received fluctuating field that passes through the Earth’s surface. These waves are echoes from the subsurface scattering source of seismic energy introduced by the Earth’s surface.
