Array grouping of seismic sensors in a marine streamer for optimum noise attenuation

摘要

A marine seismic streamer includes at least one particle motion sensor array (124). The array includes a plurality of particle motion sensors (G1-G12) disposed at spaced apart locations along the streamer. Outputs of the particle motion sensors are functionally coupled to form an array. A number of the particle motion sensors (G1-G12) and a spacing between adjacent particle motion sensors are selected to attenuate noise in a selected mode of propagation and within a selected wavenumber range. The streamer includes means for weighting a signal output of each particle motion sensor in the at least one array. A signal weight applied to each sensor by the means for weighting is selected to optimize attenuation of the noise.
