Abstract Off-line 3D seismic acquisition,developed on off-line 2D seismic,has advantages of suppressing noise.This paper discusses an off-line 3D seismic acquisition in Jiyuan loess area,Erdos Basin.Source parameters are optimized based on near surface investigation by uphole.Geological target oriented off-line 3D geometry is designed and testified.High quality 3D data cube obtained by our off-line 3D seismic acquisition shows not only its effectivity,but also oil exploration prospect in this area.
