| 摘 要： | 提出了一种利用二维地质剖面构建三维块状地质模型的方法。该方法以用户编辑的二维地质剖面为输入,寻找地质块体的拓扑关系,自动构建以地质块体为单元的块状三维地质模型。在三维块状模型的基础上,研究了三维高斯射线束正演方法。这是一种快速的地震记录合成方法,它将波动方程和射线理论紧密结合起来,通过运动学射线追踪获取射线轨迹,通过动力学追踪来获取中心射线附近的高频能量分布,因而既能反映波的运动学特征,又能表现波的动力学特点,并且具有运算速度快、精度高等优点。

| Abstract: | The ray method plays a vital role in seismic exploration.The 3-D block geological model is the base of the ray numerical modeling.However the 3-D geological modeling,especially the complex model structure usually is quite difficult.This paper proposes an algorithm to use two-dimensional geological cross section to construct the three dimensional geological model.The algorithm has effectively solved the complex geological modeling problem.Based on the first hand information about 2-D geological cross section... |
