【摘要】 本文采用数值模拟方法分别从观测系统属性、反射波能量和地震资料品质等方面分析了不同观测系统压制干扰波的效果,得出以下结论:①不同观测系统对线性干扰波具有不同压制效果,横纵比大的观测系统具有较好压制效果;②改善面元属性(方位角和炮检距分布均匀)、增大排列片横纵比,不仅能降低采集脚印,同时能更好地压制线性干扰,削弱噪声。因此数值模拟方法是一种较为经济实用的分析研究观测系统的方法,且具有较高的灵活性和适应性。更多还原

【Abstract】 In this paper,we propose a noise attenuation method by 3D geometry numerical simulation.We simulate 3D seismic acquisitions with different geometries and process the datasets with the same processing flow and parameters.The following understandings have been found:(1)Simulations show that different geometries have different capability of linear interference suppression.Geometry with larger aspect ratio gets better noise suppression.(2)Three different geometries are simulated.The results show that the geometry with smaller bin size and larger aspect ratio removes linear noise and footprints better than the others.This method is an effective and practical way to optimize geometry design.更多还原
