在地震资料数字处理过程中,通常由解释人员分析速度谱资料,确定速度随深度(或t_0时间)变化规律,提供速度参数。这项工作需要较多的人力和时间。由于速度谱快速算法的应用,使速度谱整理工作更显得繁重。因此有必要发展一种使用计算机自动整理速度谱的方法,以适应地震资料数字处理工作的需要,减轻解释人员的工作负担。本文提出的速度谱自动整理方法和IRIS 60电子数字计算机速度谱自动整理程序便是针对这一问题而提出来的。
In the digital processing of seismic data, the interpreter usually analyzes the velocity spectrum data to determine the velocity variation along with the depth (or t_0 time) and provides the velocity parameters. This work requires more manpower and time. Due to the application of the speed spectrum fast algorithm, the speed spectrum finishing work is even more heavy. Therefore, it is necessary to develop a method of using computers to automatically arrange the speed spectrum to meet the need of digital processing of seismic data and reduce the workload of interpreters. The speed spectrum auto-finishing method proposed in this paper and the auto-finishing program of IRIS 60 electronic computer speed spectrum are put forward for this problem.
