S/N improvement method for 3D seismic data; Sanjigen jishin tansa data no S/N hi kaizenho ni tsuite

Abstract

Discussions were given on a method to suppress coherent noise in data derived from a non-uniform vibration transmitting-receiving point layout in three-dimensional seismic exploration. The discussions attempted suppression of coherent noise by utilizing a prediction filter for the frequency-space zone. The prediction filter for the frequency-space zone is a filter which handles coherent waveforms found in the record as a signal, and attenuates random noise. Methods to remove coherent noise may include paralleling of signals, making the tracing order random, use of an FX prediction filter, restoration of the tracing order, and restoration of the signal positions. As a result of the discussion using a simple model, it was made clear that coherent noise distributed spatially can be suppressed and signals can be extracted by applying the frequency-space zone filter. In addition, the signals extracted by this operation were found to maintain well the original waveforms. 7 refs., 9 figs.
