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。 A new layer velocity inversion method is proposed. It synthesizes and improves the current state-of-the-art high-precision velocity analysis and estimates the formation velocity based on probabilistic model velocity inversion. The new method has the advantages of high computational speed, making full use of a priori speed information to reduce the uncertainty. The application of actual seismic data shows that the method is practical and effective.
