摘要
对红台地区油气来源、分布特征、运移通道、油气藏类型及生储盖组合等进行了研究,通过红台2与红台6的油气藏对比分析,认为该区主要发育岩性-构造复合油气藏、岩性上倾尖灭油气藏及岩性透镜体油气藏。红台6油气藏发育的鼻状构造脊线为低势区,是有利的油气运移通道和油气运移的指向与汇聚地点。通过对鼻状构造油气富集规律和条件的研究,认为鼻状构造油气富集的条件除构造因素外,还受生油条件、沉积相带等因素的影响。
The Hongtai oilfield in Tuha Basin is studied for hydrocarbon origin,distribution,migration pathway,reservoir type and the assemblage of source-reservoir-seal.The correlation and comparison between Hongtai 2 and Hongtai 6 reservoirs indicate that the reservoirs developed in this oilfield mainly include lithologic-structural hydrocarbon reservoir,lithologic updip pinchout hydrocarbon reservoir and lithologic lenticular hydrocarbon reservoir.The hinge line of the nose structure in the Hongtai 6 reservoir is a low potential zone,a favorable migration pathway and hydrocarbon accumulation site.The study shows that besides tectonic factor,the hydrocarbon accumulation in the nose structure was also subject to oil source condition and sedimentary facies.
