摘要
二叠系油藏的发现具有重要的理论与实际意义。不仅突破了下扬子古生界的油气发现,而且完善了下扬子区上组合的晚期生烃、晚期成藏理论,使下扬子古生界油气勘探工作得以重启。黄桥地区龙潭组顶部致密砂岩油藏具有与CO2气伴产的特性。通过大量最新地震钻井勘探发现的资料,岩石薄片鉴定、物性和测井资料解释以及油气流体包裹体的资料,综合分析了该区上古生界油藏的成藏模式与油藏类型的特征,提出了针对储量评估与有效开发制约因素的对策。
The discovery of Permian hydrocarbon reservoir is of theoretical and practical significance for oil exploration in the Lower Yangtze region.It is not only the first discovery in the Palaeozoic in the region,but also a valuable case for the study of hydrocarbon accumulation model and reservoir-forming mechanisms in the upper group in later stage.The tight sand reservoir found at the top of the Longtan Group of Huangqiao block contains a substantial amount of CO2.Based on the newly acquired seismic and well drilling data,plus the investigation of petrographic sections,physical properties,logging data and hydrocarbon fluid inclusions,we made an integrated study on the characteristics of the Neopaleozoic hydrocarbon reservoir and an accumulation model is proposed.
