Abstract:In recent years,seismic data quality has been improved by high density 2D acquisition in high-steep structural zones of Huangguamao-Huangshi,Qaidam Basin. But data quality in some other areas is still very poor and cannot meet geological task requirements. Based on seismic data in Huangguamao,Mangdong,and Huangshi,the main factors that affect data quality are recognized by forward modeling. In order to improve seismic data quality in this kind of areas, we propose an idea of high-density wide line and other measures including broadband point source,small receiver interval,and reasonable line spacing. Field applications demonstrate that the proposed idea and measures have achieved good data quality in high-steep structural belts in Qaidam Basin.
