摘　　要：在深入研究古近系定远组烃源岩有机地化特征、分布规律及沉积环境的基础上,通过与相似盆地对比,认为古近系烃源岩主要为成水湖相沉积,受控于盆内近 EW 向的次级断层,尢以南部保存较好,具有低碳、高"A"、高 S_1的特点,与我国的江汉、柴达木等古近系含盐盆地具有相似的有机地化特征,其成烃转化率高,热演化程度适中,资源潜力较大。古近系是区内油气勘探突破的重要目的层系。On the basis of deeply study of organic geochemical characteristic,distribution law and deposit environment,and contrasting with resemble basins,the hydrocarbon source rock of Dingyuan Formation, Paleogene was thinked as saline lake-facies sediments,controlled by the nearly EW-trending secondary faults in the basin,and well preserved especially in the southern part,and possessing the low carbon,high'A'and high SI,having similar organic geochemical features to those in the Paleogene salt-bearing basins such as Jianghan and Chaidamu.Their hydrocarbon-conversion rate is high,thermal evolution extent moderate,and resources potential great.The Paleogene is the important target stratum for the breakthrough of the oil and gas exploration in the area.
