Application of explosive-vibroseis combined efficient acquisition technology in complex loess mountain area
With the continuous development of seismic acquisition technology of"2W1H",several explosive-vibroseis com-bined seismic acquisition projects have been successfully carried out in Ordos Basin,where vibroseis has played a great advan-tage.However,there are still many challenges on achieving the high integration and efficient acquisition of explosives and vibro-seis.It is mainly manifested in the poor uniformity of point layout,low application rate of obstacle area,and difficulty in impro-ving acquisition efficiency.Through the technical research and analysis of 3D seismic exploration projects in complex loess mountain areas in recent years,advanced technologies such as explosive-vibroseis combined high-precision pre-plan design and VPM+SSC explosive-vibroseis combined dual-source excitation are summarized.The above technologies have been successfully applied in the 2022 NXX 3D project in the Ordos Basin and have achieved remarkable results.It creates a new situation of explo-sive vibroseis combined with an efficient acquisition in loess mountain area.
