摘　　要：油气成藏期研究是油气成藏研究的热点和难点之一,在分析四棵树凹陷油气藏烃类流体、目的层流体包裹体等资料的基础上,应用含油气构造演化史法、烃源岩演化史法和储集层有机岩石学法,对四棵树凹陷油气成藏期进行了综合分析。沙湾组油藏和安集海河组油藏成藏时间较晚,于新近纪早期开始成藏;齐古组油藏和紫泥泉子组油藏从古近纪末期开始成藏,其主成藏期为沙湾组地层沉积时期。在上述工作的基础上,对四棵树凹陷的成藏过程进行了综合分析,指出了该凹陷的勘探潜力和方向。Study on reservoir-forming stage was one of the most important parts of hydrocarbon accumulation study.Through the analysis of pore fluid and fluid inclusion of Sikeshu Sag,reservoir-forming stage,the methods of evolutional histories of oil-gas structures and source rocks and method of reservoir organic rocks were used for a comprehensive analysis of reservoir-forming stages of Sikeshu Sag.Oil pool in Shawan Formation and Anjihaihe Formation began to accumulate at the early stage of Neogene.Oil pool in Qigu Formation and Ziniquanzi Formation began to accumulate at the late stage of Paleogene and the main reservoir -forming time was 15～10My.The characteristics of hydrocarbon accumulation are analyzed,and the potential and the exploration direction of Sikeshu Sag are pointed out.
