Research on Vz Noise Recognition and Suppression Technology Based on Four Components of Submarine Nodes
The suppression of"shear wave leakage noise"or"Vz noise"is one of the key steps in the de-noising process of submarine node seismic data processing.The usual method is to suppress Vz noise completely in Z component based on P component pattern.However,in practice,it is difficult to suppress the Vz noise completely through the noise model of P component architecture.Therefore,this paper makes full use of the advantages of four components of OBN(Ocean Bottom Node)data,and proposes a processing method that combines R,T and P components for pattern recognition and model construction of Z component noise,and then suppress Vz noise.This method can better extract shear wave noise in Z component,which has better denoising effects compared to the original method.
