Abstract
Since seismic acquisition, especially 3D high density seismic acquisition, is a costly and time-consuming task, it has always been one of the most concerning point to improve efficiency and reduce cost in industrial prospection. For high density seismic acquisition in mountain areas, drilling source wells and positioning and relocating survey lines are key factors influencing working efficiency. This abstract introduces a 3D high density seismic acquisition case in southern margin of Junggar basin. By using source with small explosive quantity in shallow well and point receiver, efficiency of the 3D high density seismic acquisition was improved significantly, and acquired seismic data has higher quality to image complex structure and minor faults more clearly than the old seismic data.
