模型反演折射静校正方法及软件技术

THE METHOD OF REFRACTION STATIC CORRECTION USING MODEL INVERSION AND SOME SOFTWARE TECHNIQUES

本文叙述了模型反演折射静校正的一般原理。首先介绍了折射初至波的自动拾取，其次介绍了最佳拟合旅行时反演。在软件实现中本文提出了几项技术包括提高初至拾取的准确率及初至结果的质量评价，如何使系统对不同地震数据格式具有通用性；静校效果的初步评估。本文的方法和技术在实际生产应用中广泛使用。

This paper introduced the general theory of refraction static correction using model inversion. First, a method of firstbreak automatic picking is introduced. Second it is the inversion of travel time best fitting. Then, some software techniques are put forward such as: How to improve the accuracy of firstbreak picking; How to let system fit different seismic data format; Inital check the result of Static correction. The method and techniques above mentioned are now widely used in field work. One example illustrated the effection.
