摘要
巴彦浩特盆地沙漠区的二维地震资料原始信噪比低、静校正量大,针对该区资料特点,在资料处理中采用了低降速带模型与交互迭代静校正,F-K速度滤波,区域异常振幅衰减,地表一致性补偿,人工交互拾取叠加速度,保护浅层信息,衰减随机噪声等技术为主的处理流程和手段,获得了较好的处理效果,为地质解释人员提供了较高信噪比的地震剖面。
The initial signal/noise ratio of the 2-D seismic data acquired in the desert areas in Bayanhaote Basin are low,and the amount of static correction is large.In accordance with these datu characteristics,the following methods are applied in data processing: low-velocity layer and velocity-reducing layer modeling and interactive iterative statics, F-K velocity filtering,regional abnormal amplitude attenuation, surface-consistent compensation, manual interactive stacking velocity picking, shallow layer information protection, and random noise attenuation.Seismic sections with high signal/noise ratio are abtained with these methods.
