本文在研究目前三维地震勘探中常用的低速带静校正算法的基础上, 根据几年来低速带静校正处理情况, 研制出一种计算三维地震勘探低速带的静校正系统, 简述了这种处理系统的原理, 并对吉林油田某三维地震工区的低速带资料进行了处理。结果表明, 该系统计算速度快、精度高、实用性强, 对改善地震剖面质量和提高信噪比是有效的。

Basod on a review of low velocity layer static corrcction algorithms commonly used in 3-D seismic survey and experiences of recent years,we have dcveloped a LVL static correction system.The paper briefly describes the principle of this processing system and applics it to processing the data of low velocity layer in a 3-D seismic work area of Jilin Oil Field. The results show that the system brings fast operation, high accuracy, and is effective in improving tho seismic scction quality and S/N ratio.
