| Abstract: | Based on the regional geological background in the North Yellow Sea Basin and the principle of velocity analysis,we obtained the information of interval velocity,average velocity,sand content,etc,which was used to interpret and calculate the velocity spectrum of the north Yellow Sea basin.These velocity data were made use of distinguish from time after time wave and sag area and rise area,time-depth conversion,tectonic analysis,lithologic analysis.This conclusion will provide a reliable basis for seismic data interpret and lithofacies division and appraisal of petroleum and natural gas resources in the north Yellow Sea Basin. |

| Keywords: | The North Yellow Sea Basin interval velocity time-depth conversion sand content Lithologic analysis |
