【摘要】 在地震资料信噪比比较低，叠加次数比较低的情况下，常规处理效果不好，可以采用分频处理。各个不同频带的地震反射波周期差别较大，分别进行自动剩余静校正及互相关静校正，能准确求出剩余时差。在各个频带内做反Ｑ补偿及自适应倾斜面之叠加，可以更好的进行频率补偿及相位补偿，增加叠加次数，提高处理质量。在上述处理基础上，将各频带的地震反射能量相加，获得最终叠加剖面，提高处理效果。更多还原

【Abstract】 In the case that the signal-to-noise ratio and the number of times of superimposition are both rather low, the routine processing is not effective, and frequency division processing may be used. Seismic refleceted wave periods of different frequency bands show remarkable differences, and hence the separate automatic residkual statics and cross correlation statics could accurately evaluate residual time difference, the teverse Q compensation and the superimposition of edaptive oblique plane elements could perform frequency compensation and phase compensation in a better way, increase the number of times of superimposition and raise the processing quality. On the basis of the above-described processing, the seismic reflection energies of various frequency bands are added to each other to obtain the final superimposition profile and raise the processing effect.更多还原
