Adaptive Predictive Deconvolution Technique Application in Marine Seismic Data Processing

For reverberation commonly seen in the sea, interlays multiple wave and other common short-period multiple, there are more residual if using the method of predictive deconvolution attenuation multiple wave. It proposes the new method of adaptive predictive deconvolution that prediction step and the factor length can set by different multiple wave distribution cycle and scope automatically. It can be found in model comparison test that the method has especially obvious effect on processing of interlayer multiple waves with strong energy and unobvious wave group characteristics. It has verification on actual data and makes analysis and comparison of some key obtained results maps. It shows that it has good prospect on the method.
