【摘要】 复杂地表共反射面元(CRS)叠加技术可以直接应用于未作静校正的数据。在基准面重建时,利用CRS运动学波场参数可将CRS叠加剖面校正到某一选定的水平面上。在复杂地表CRS叠加中,波场三参数的耦合需要用到组合参数优化策略,因此实际处理过程中采用模拟退火算法来实现。地震数据的试算表明,复杂地表CRS叠加得出的剖面比常规处理剖面有较高信噪比和同相轴连续性。另外,对CRS叠加技术的几个发展方向和研究热点进行了总结。更多还原

【Abstract】 Common reflection surface (CRS) stack method that takes into account the effects of rugged topography can be applied directly to the prestack data without static correction. In reda-tuming, CRS-stacked ZO section can be scaled to a chosen planar measurement level with kinematic wavefield attributes. Because of the three kinematic parameters coupling with each other, we used simulated annealing algorithm to solve the problem. Model data and real data tests indicate that the results are much better than those of conventional stack in terms of S/N ratio and continuity of reflection events. This paper summarized the developing trends and hot issues of common reflection surface stack.更多还原
