China University of Petroleum, Beij ing 102249, China;2.Research Institute of Exploration and Development, Daqing ilf ield Limited Company, Heilongj iang 163000, China) Abstract:Qijia Sag is one of the i portant petroleu generative depressions in the Songliao Basin, and the Fuyang oil for ation is the ain oi-l bearing for ation. Different opinions existed on oil sources of the Fuyang oil for ation in the northern Qijia Sag. By eans of oil population division and oi-l source correlation, it is showed that the crude oil of the for ation originated fro the local Qingshankou No. 1 For ation. It negates the viewpoint of igration. In the past 40 years, it was believed that the sags on both sides supplied the oil of Daqing Placanticline. Oi-l oil and oi-l source correlations reveal that there is low ature authigenic oil in the placanticline,which proves that low ature source rocks havethe genetic potential in Daqing Placanticline. Key words:Songliao Basin;Qijia Sag;Daqing Placanticline;crude oil;oil sources 　　, () 。2002 ,708 ,19.244t , 。 , 。 40 , [1] ———— 。 , 。 1
