Abstract

Abstract

The fault system in the Zhusan Sag area of the western South China Sea is complex. The seismic data acquired at different exploration stages has a narrow azimuth,and it is difficult to image the complex fracture zones. The seismic data with different azimuths in the same batch need higher operation technology and higher cost.In order to achieve the purpose of wide-azimuth seismic imaging,3D seismic data acquired in different orientations in different years can be combined with advanced multiple suppression technology and seismic fusion technology to indirectly form a wide-azimuth 3D seismic data. This operation will greatly reduce the acquisition cost. The comparison and analysis of the actual imaging effect indicate this method can better improve the imaging effect of the complex fracture zone.
