在二维背景中模拟三维地震数据的需求,促使人们开展了所谓的2.5维模拟方法的研究。其中,Liner曾提出一种用于常密度介质的近似2.5维波算子法。 用Liner的2.5维波动方程高频渐近射线序列(WKBJ)分析法预测的旅行时和振幅与用Bleisten研究的用于常波速介质的2.5维射线理论预测的结果 The need to simulate 3D seismic data in a two-dimensional background has prompted the development of so-called 2.5-D modeling. Among them, Liner has proposed an approximate 2.5-dimensional wave operator for a medium of constant density.
