摘要: 随着地震勘探区域地质条件复杂化,静校正在资料处理中的作用日显重要.本文模拟研究了折射波在不同地质条件中的特性,完成了正演模型下的折射波静校正量计算,并将静校正后记录与理论模型记录对比,分析该方法的准确性,总结折射波静校正方法的技术难点,提出一种更准确优越的解决方法.最后,运用该方法选取最合理的参数,并配合先进的处理软件对实际资料进行处理,有效地消除了长波长剩余静校正量,得到了较高质量的叠加剖面.

Abstract: With the regional geological conditions of seismic prospecting in complex, static correction in data processing becomes more and more important. The paper studies the characteristics of the refraction wave with different geological conditions by simulation. Refraction statics have been calculated based on forward modelling after correlation processing. With the accuracy of this method after comparison and analysis of corrected records and theory model records, technical difficulties of this method are concluded and a more accurate and superior solution is submitted. At last, with the most reasonable parameter selected and the advanced processing software used, real data is processed by this method, and long wavelength residual statics are eliminated effectively,and the high-quality stack profiles can be obtained.
