摘　　要：对松辽盆地古龙凹陷葡萄花油层烃源岩埋藏史、古构造演化史、油气运聚场、储层沉积特征和油水分布规律等进行了综合分析。认识如下:葡萄花油层油气主要来自下伏青山口组一段源岩,油气成藏关键时期为明水组末期;总结出葡萄花油层顶面古构造演化的4个主要阶段;葡萄花油层油气富集的2种主控因素。The authors comprehensively analyze the buried history of the source rocks,the palaeotectonic evolution history,the migration and accumulation field of hydrocarbon,the reservoir sedimentary characteristics and the oil-water distribution rule in the Putaohua reservoir of the Gulong depression in the Songliao basin.The result showed that： the hydrocarbon of the Putaohua reservoir was mainly derived from the underlying source rocks of theⅠsegment of the Qingshankou Group,the key stage of hydrocarbon accumulation was at the end of the Mingshui Group.The Putaohua reservoir top has undergone four stages of palaeotectonic evolution,two chief factors that control the hydrocarbon enrichment in Putaohua reservoirs has been summarized.
