Abstract：Horgos overthrust structural belt is in piedmont of north Tianshan Mountain >south margin of Junggar basin.Although after many years,seismic exploration,the little effects are produced because of very complex seismic-geologic conditions in that region.In new round of tackling the key problems of seismic exploration developed in 2003 in Horgos region,according to the characters of complex near-surface and underground structures,we used high-precision-satellite-photo-aided design of acquisition scheme;adopted a new exploration ideas such as flexible and viriable geometry,fold,shooting pattern,shooting factor and adaptable static corrections methods;drew up technical operation scheme that proceeded from the practical situation and took acquiring good seismic data as an object,which resulted in good effects and mainly showed as follows:strong reflected energy and high S/N ratio at the targets;distinguished fault characters and overthrust plane;the blind zone in north flank of Hordos structure on the former seismic sections disappeared and clear relation between shallow and deep local structures appeared.
