摘要

The system of coil to acquire seismic data, dispersion of marine research, seismic source system, and method for acquiring seismic data.System for acquiring seismic streamer seismic data includes a plurality of first sections of cable employing a first sensor configuration.And at least one second section of cable operatively connected to one or more of the first cable sections, and by using a second configuration of the sensor.In various system configurations of coil, one or more of the second sections of cable are integrated very sparsely in the serpentine arrangement of coils and / or seismic dispersion.The first sensor configuration may include, for example, a distribution in conventional hydrophones and the second sensor configuration may include, for example, multi-component sensors.As at least one of: particle sensor speed sensor; pressure gradient; accelerometer; and a combination of these.The present invention is useful for attenuating noise in seismic data measured, so as to eliminate the ghosts of the data.A particular case of elimination of ghosts includes decomposing part upward and downward part of the vertical component of the velocity of particle associated with the reflections of acoustic wave paRtir a stratum.
