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 low signal-to-noise ratio and large static correction of 2D seismic data in the desert area of Bayanhot Basin are large. According to the characteristics of the data in this area, the low-speed model and the iterative static correction, F-K velocity filtering , Regional anomalous amplitude attenuation, surface coherence compensation, artificial interaction stackup superposition speed, protection of shallow information, attenuation of random noise and other technology-based processing flow and means, get better treatment effect, provide more explanation for the geological interpreter Seismic profiles with high signal-to-noise ratio.
