Abstract

Abstract:

In land seismic survey, multiple reflections, like other interference waves, interfere with primary reflections and reduce the signal to noise ratio of seismic data. According to the property of multiples in the land based seismic data, a processing strategy which combines stacking and the f－k filtering for multiple attenuation was proposed. Firstly, stacking with velocity functions from the primaries partially to attenuate the energy of multiples in the original seismic data, and determining the CMP ranges with residual multiples by stacked sections, and then the f－k filtering was applied to the CMP gathers with residual multiples along the profile for suppressing multiples. The results of synthetic and field seismic data processing show that the strategy is not only effective for multiple attenuation in this land seismic data, but also reduces the injury for the primary reflections during data processing.
