Design and Application of Air-gun in Stream Wide Azimuth Multi-source Seismic Acquisition

Aiming at the requirement of multi-source seismic acquisition and the limitation of existing equipment, the key technology of gun array design is studied. Under the condition of different gun frame and gun volume, we simulated and analyzed the wavelet by a large number of different air-gun array, therefore different volume of gun array sources were designed which stimulated various combinations of air-gun with the same wavelet characters and consistent energy. The combinations of source arrays designed for different gun holders and accessories are applied to the wide azimuth multi-source seismic acquisition project. The energy and spectrum of the actual seismic data collected reach the expected goal, which shows that the designed source array meets the requirements of wide-azimuth multi-source seismic data acquisition.
