摘要
本文根据叠加速度随DMO速度的变化关系，构造一种适用于任意地质构造的速度分析方法。它克服了传统基于NMO双曲线的速度分析其法只适用于水平层状和速度横向不变介质的不足。与叠前偏移速度分析其法相比，本算法运算量小，占用计算机资源少，而且容易实现。
The velocity analysis method that ls suitable to any geological structure is put forward on the basis of variation relatlon between stack velocity and DMO velocity.The method breaks through the limltatlon that NMO hyperbola-based velocity ana-lysis procedures are only applicable to horizontal layered medium where seismic ve-locity is laterally constant. This easy method takes less operation and less computer resources than prestack methods for migration velocity analysis.
