reflection point meaning in Chinese
反射点
Examples
- The reflection point will, generally, not lie vertically below the observation point .
一般情况下，反射点并不在观测点的正下方。 - The reflection points for the transformed waves do not coincide with those of the non-transformed waves .
转换波的反射点与非转换波的反射点不一致。 - Based on the similarity of common reflection point trace gathers in one coherent zone , crs stack can focus more energy on the vicinity of the reflector , and therefore can obtain a high signal - to - noise ratio zero offset section by stacking events with the same phase
共反射面叠加利用了邻近多个共反射点道集的相似性，提高了资料的覆盖次数，从而压制了随机噪声，增强反射波同相轴的连续性，大幅提高了地震资料的信噪比。 - For processing of 3d and 3c seismic data , the reflected p - waves can be processed with the conventional methods , while the reflected converted waves can not be processed with the conventional p - wave processing methods , because their travel paths are asymmetrical , their common midpoint gathers are no longer common reflection point gathers , and their time - distance equation is non hyperbolic
在三维三分量地震勘探资料处理中，对于反射纵波资料可以采用常规方法进行处理；而对于反射转换波资料，由于其传播路径的非对称性，转换波共中心道集不再是共反射点道集，转换波时距方程也不是双曲方程，因此不能采用常规纵波处理方法来处理转换波资料。 - This paper proposes a method for optimizing the parameters of geometry system . based on the ray tracing for the built - model , discussing and analyzing the parameters of geologic aim such as the bin size , calculating the fold of aim layer ' s common reflection point , comparing the fold of crp with the fold of common mid - point , the geometry system ' s parameters are adjusted to improve the low fold bins , the quality of data collection and effect of exploration
本文提出了首先建立目标地质体的数字模型，根据射线追踪正演分析，目标地质体的参数分析(面元分析等) ，统计求取复杂地质模型目标层真正的共反射点覆盖次数，比较cmp面元与实际crp面元的覆盖次数差异， cmp道集对应的共反射点面元分析，针对覆盖次数较低的目标层面元调整和优化观测参数，提高目标层的采集质量和勘探效果。
