Abstract:The residual interval velocity in Manite depression in Erlian basin is obtained by subtracting regional integrated velocity from the corresponding interval velocity taken from seismic velocity spectrum,The residual interval velocity versus sand percent content can be plotted by correlating the residual interval velocity with the sand percent content obtained from drilling data.The comprehensive analysis of the residual interval velocity versus sand content,seismicstructural map and isopach map, etc.can indicate lithologic distribution,depositional environment and source area thus,hydrocarbon generation condition,reservoir condition and the favourable hydrocarbon一bearing area can be predicted。In general,this result accordswith that of seismic stratigraphic interpretation.
