反射波至旅行时反演以地震波长相当的精度重构了主要界面的结构。常规叠加速度分析分辨率较低、即地震排列长度的等级降低。进一步而言,叠加速度场是在时间域内定义的,转换为深度域并不简单。有两种方法可以提供选择:用叠前反射同相轴这是相当困难和费时的,而用速度谱却又是简单低廉的。因此就费用和优点而言,在这两种方法间有一种折衷的方案。本文中,我们通过复杂性逐步增加的不同的合成模型的使用,比较了这两种方法的主要特点。我们使用傅里叶伪谱法模拟了有关地震记录。 Reflected Waves to Travel Inversion Reconstructs the structure of the primary interface at seismic wave-like accuracies. Conventional superposition velocity analysis resolution is low, that is, the level of seismic arrangement length decreases. Further, the superimposed velocity field is defined in the time domain, and converting to a depth field is not easy. There are two options to choose from: It is quite difficult and time-consuming to reflect the events by the prestack, but the speed spectrum is simple and inexpensive. So in terms of costs and benefits, there is a compromise between the two approaches. In this paper, we compare the main features of these two approaches with the use of different synthesis models with increasing complexity. We use Fourier pseudospectral simulation of the related seismic records.
