本文叙述了利用射线追踪法生成多层曲界面三维正演模型的方法和原理。根据上述原理,在PDP11/45计算机上进行了试算,给出了三个模型实例,并对其在时间剖面上的三维地震响应进行了分析。

In this paper, the principle and method of creating 3-D curved multi-layer interfaces in forward modelling by ray-tracing were described. In line with this, the trial and error calculation were implemented on computer of Moddel PDP 11/45 and 3 examples were given. In addition, the 3-D seismic response in time section were studied and examined.
