Abstract:The Minhe basin is characterized by strong fluctuation of geography and large variation of near-surface lithology both in vertical and lateral directions,forming strong wave impedance interface between the loess cover coat and the underlying old layers,resulted in seriously non-consistent issue for shooting and receiving condition of seismic waves,developing such interference waves as plane wave,shallow refractions,sidewipe and scattering characterized by strong energy and slow attenuation,all these resulted in extremely low S/N ratio on legacy single-shot raw records.The good results have been seen after layout of multi-information broken straight line,optimizing shooting factors,high-density seismic acquisition,fine near-surface survey and static corrections,which has new knowledge for structural feature and resource potential of Minhe basin.
