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。这项工作需要较多人力和时间。目前,胜利油田规划院计算室研制成功速度谱快速算法,为开展大量速度分析工作,特提是为地震资料变速处理,提供了强有力的手段,但这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。自1976年以来,我们和胜利油田地调指挥部、油田规划院计算室协作在这方面开展了专题研究工作,并取得了一定成果。现将速度谱自动整理方法和IRIS60电子数字计算机速度谱自动整理程序介绍如下。
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. At present, the Shengli Oilfield Planning Institute has developed a fast calculation method of speed spectrum in the calculation room. In order to carry out a large number of velocity analysis work, TTI is a powerful tool for seismic data processing. However, it makes the work of velocity spectrum more complicated. Therefore, it is necessary to develop a computer-based method to automatically arrange the speed spectrum to meet the needs of digital processing seismic data and reduce the workload of interpreters. Since 1976, we conducted special research in this area in cooperation with the command and command department of Shengli Oilfield and the calculation room of the Oilfield Planning Institute, and achieved certain results. The speed spectrum finishing methods and IRIS60 electronic digital computer speed spectrum finishing procedures are as follows.
