用计算机自动拾取叠加速度,并进而得到层速度等信息,对实现地震资料处理自动化和计算机进行综合地质解释有着十分重要的意义。在文献[1][2]中,曾先后提出过利用图的最小生成树的模型和方法自动拾取叠加速度,并取得了一定的效果。本文研究了一种新的自动提取叠加速度的方法:极小化拾取风险的最佳搜索算法。 通过对实际资料进行试验,结果表明方法是有效的,现已作为一个模块引入PDP-11/45的prospector系统中,并在生产中试用。
The computer automatically picks up the superposition speed, and then get the layer velocity and other information, it is very important to realize the automation of seismic data processing and computer comprehensive geological interpretation. In literature [1] [2], it has been proposed that the model and method of using the minimum spanning tree of the graph have been used to automatically pick up the superposition speed and achieve some results. In this paper, a new method of automatically extracting superposition velocity is studied: the best search algorithm to minimize the risk of picking up. The actual data was tested and the results showed that the method was effective and has now been introduced into the prospector system of PDP-11/45 as a module and tested in production.
