摘要
为了研究南堡凹陷东一段油气成藏规律,在输导油气机理和能力影响因素分析的基础上,利用所建立的断裂输导油气能力评价方法,对其油源断裂分布及输导油气能力进行了定量评价。结果表明:研究区发育有大量的油源断裂,在柳赞、高尚堡、老爷庙、南堡1号、南堡2号及其以东地区、南堡4号及其以南地区、南堡5号以东地区,油源断裂输导油气的能力相对较强,这有利于下伏沙三段或沙一段—东三段源岩生成的油气在上覆东一段中聚集成藏。目前,在这些地区的东一段找到了大量油气,证明了使用该方法来研究油源断裂输导油气能力是可行的。
In order to study hydrocarbon accumulation of Ed1 in Nanpu Depression,based on the study of influence factors of the mechanism and ability of hydrocarbon transport,combined with the evaluation method of hydrocarbon transport ability of fault,the distribution of faults connected with source rocks and hydrocarbon transport ability of Ed1 in Nanpu Depression were studied.The result shows that there are a lot of faults connected with source rocks developed in Ed1.The hydrocarbon transport ability of faults connected with source rocks in Ed1 in Liuzan,Gaoshangbu,Laoyemiao,the east of Naupu 5 region,Nanpu 1 region,Nanpu 2 region and its eastern area,Nanpu 4 region and its southern area are stronger than that in other region,which is favorable for the hydrocarbon generated in Es3 or Es1-Ed3 source rocks migrated into Ed1 and accumulated there.At present,there are a large number of hydrocarbons found in theses areas,which proves the feasibility of this method to study hydrocarbon transport ability of faults connected with source rocks.
