High frequency reconstruction technique based on auto gain control modulation
基于自动增益控制调制法的高频重建技术

To solve the problem that the seismic data resolution can't meet the request of reservoir prediction in the river face thin-layers in Chinese eastern oil fields,a high frequency data reconstruction method is proposed.The extrema of the seismic data are used to get the modulation function which operated with the original seismic data to get the high frequency part of the reconstruction data to rebuild the wide band data.This method greatly saves the computation,and easy to adjust the parameters.In the output profile,the original features of the seismic events are kept,the common fault that breaking the events and adding new zeros to produce alias is avoided.And the interbeded details are enhanced compared to the original profiles.The effective band of seismic data is expended and the method is approved by the processing of the field data.
