摘要: 通过平衡剖面法、流体包裹体分析、地化分析以及物性测试对下扬子黄桥地区的构造演化、油气成藏史、成藏类型及成藏主控因素进行了研究。黄桥地区构造演化经历了平稳隆降、挤压推覆、拉张裂陷3大时期;黄桥地区存在2期油气充注的历史,燕山晚期至喜山期油藏形成,晚喜山期上古生界内幕油气藏得以保存并最终定型。该区HT3井油藏属于龙潭组自生自储型油藏,构造是油气成藏的主要控制因素,物性是控制油藏分布的重要因素。Abstract: The tectonic evolution,petroleum accumulation history,accumulation type and main controlling factors in Huangqiao region of the Lower Yangtze Basin were studied with the balanced cross section,fluid inclusion,geochemical and physical analysis methods.The tectonic evolution in Huangqiao region experienced 3 stages including the stable uplift and deposition,the extrusion and nappe,and the extension and rift.2 periods of petroleum filling took place in the region.From the late Yanshanian to Himalayan,petroleum accumulated.During the late Himalayan,the reservoirs in the Upper Paleozoic were saved and finally formed.The reservoirs found in well HT3 belong to Longtan Formation.They were self-generated and self-reserved.Structures controlled petroleum accumulation.Physical properties influenced reservoir distribution.
