摘要
提出一种新的层速度反演方法。它综合并改进目前先进的高精度速度分析方法和基于概率模型速度反演方法来估算地层层速度。新方法具有计算速度快,可充分利用先验速度信息以降低不确定性等优点。实际地震资料的应用表明,该方法实用且有效。
The new method for seismic interval velocity inversion has been proposed in the paper, which combines and improves the advanced high resolution velocity analysis method and seismic velocity inversion method based on probabilistic models to estimate interval velocities of thick layers. It has the advantages of computing fast and combining suitable a priori velocity informations to reduce uncertainties of the solution. The applications in field data show the method developed in the paper are satisfactory, practical and efficient.
