  • Based on the characteristics of triaromatic steranes, alkyl triaromatic steranes and stable carbon isotopes, the sources of the condensates were analyzed in Paleogene in Hongzhuang Oilfield in Qintong Sag, Northern Jiangsu Basin. It shows that the condensates have not genetic affinity with Paleogene source rocks and were mainly sourced from the deep sources rock in Hongzhuang Oilfield. Based on the characterizations of hydrocarbon inclusions and homogenization temperatures, combining with the strata burial history, the time of hydrocarbon accumulation were confirmed in Ed1 reservoirs in Qintong Sag, North Jiangsu Basin. The result shows that cogenetic aqueous inclusions from quartz in sandstone in Well S245 show homogenization temperatures ranging from 80 to 110 ℃ and petroleum filling began Late Miocene, approximately 6 Ma ago.

Abstract: Based on the characteristics of triaromatic steranes, alkyl triaromatic steranes and stable carbon isotopes, the sources of the condensates were analyzed in Paleogene in Hongzhuang Oilfield in Qintong Sag, Northern Jiangsu Basin.
