摘要
以准噶尔盆地乌伦古坳陷二维地震勘探工程为基础,系统分析了以往地震勘探成果及存在问题.提出了高密度宽线采集、低频可控震源激发、综合静校正、聚束滤波多次波衰减等技术方案.有效提高了石炭系顶界面成像效果和内幕构造特征,为落实乌伦古地区烃源和有利构造提供了可靠依据.
The previous seismic exploration results and existing problems were analyzed systematically based onthe two-dimensional seismic exploration project in ulungur area,Junggar Basin in this paper. We developedsome technical schemes,such as the acquisition of high density and wide-line,low frequency vibroseis,compre-hensive static correction and multiple attenuation of spotlight filtering. It effectively improves the imaging effectof the top interface of the Carboniferous and the characteristics of the inner structure,and provides a reliable ba-sis for the implementation of hydrocarbon sources and favorable structures in the Urengu area.
