基于最优化方法的共反射面元叠加

共反射面元叠加可以直接由多次覆盖反射数据得到零炮检距剖面，不依赖于速度信息。通过对共反射面元叠加优化方法进行改进，大大提高了共反射面元叠加三参数分析的精度。同时引入模拟退火全局优化算法，有效地解决了新优化方法中遇到的组合优化的难题。基于CRS参数搜索的具体问题，对模拟退火算法中的三函数两准则做了最优设计。模型数据的试算和实际资料的处理结果验证了新优化方法的有效性和实用性。

Common reflection surface stack based on optimization method

The common reflection surface(CRS) stack provides a simulated zero-offset section from seismic multi-coverage reflection data,and does not depend on a macro-velocity model.The quality of three common-reflection-surface parameter sections is increased by the improvement on optimization algorithm of common-reflection-surface stack.Meanwhile,the introduction of simulating annealing algorithm which is a kind of global optimization algorithm solves the difficulty in combination optimization of new method effecti...
