摘要:
如何得到高分辨率的叠加速度谱是高分辫率地震资料处理的关键。在常规速度分析基础上,介绍了自助 速度分析法,它可以很大程度地提高叠加速度谱分辨率。理论及实例证明,该方法具有分辨率高、稳定性强的特 点,提高了速度估算精度,特别在中浅层、大偏移距或薄层的情况下,也有很高的分辨率。得到的速度为后续步 骤的工作顺利进行提供了保障。
Abstract:
How to obtain high resolution P-wave velocities is a key in the seismic data processing. Based on conventional velocity analysis, the bootstrap procedure introduced is a computer-intensive technique for assigning measures of accuracy to statistical estimates. The method can greatly improve resolution of the velocity spectra. The tests of synthetic model and processing of real data show that this method has high resolution and robust stability, which may increase the calculating accuracy of the velocity spectra. Therefore, the picking velocities can ensure the latter processing.
