摘要(Abstract)：

为了研究含油气盆地斜坡区断裂附近油气分布规律，在油气成藏期活动断裂对砂体输导油气阻止作用机理及部位研究的基础上，通过确定油气成藏期断盖配置封闭部位、断裂填充物侧向封闭部位和砂体输导油气优势路径，三者叠合建立了一套油气成藏期断裂对砂体输导油气阻止作用部位的预测方法。实例应用结果表明：油气成藏期活动的敖古拉断裂对萨尔图油层砂体输导油气阻止作用的部位共有6处，自西南至东北均匀分布，是东侧古龙凹陷青一段源岩生成油气在敖古拉断裂附近萨尔图油层聚集成藏的有利部位，与现今敖古拉断裂附近萨尔图油层的油气显示情况基本相同，证明此方法针对油气成藏期活动断裂对砂体输导油气阻止作用部位的预测是可行的。
In order to study distribution laws of oil and gas near faults in slope area of hydrocarbon basins, based on the study of mechanism and locations of active fault preventing oil and gas transport in sand bodies during accumulation period, by determining and superpositioning sealing location of fault-caprock configuration, lateral sealing location of fault fillers and dominant path of oil and gas transport in sand bodies during hydrocarbon accumulation period, a set of prediction method for active fault preventing locations of hydrocarbon transport in sand bodies during accumulation period is established. Case application shows 6 locations of active Aogula Fault during hydrocarbon accumulation period preventing oil and gas transport in sand bodies of Saertu reservoir, with uniform distribution from southwest to northeast, which are favorable locations for oil and gas generated from source rocks of Qing-1member of Qingshankou Formation in eastern Gulong Sag to accumulate in Saertu reservoir near Aogula Fault, being generally same as current oil and gas shows in Saertu reservoir near Aogula Fault, and proving the feasibility of this method for predicting active fault preventing locations of hydrocarbon transport in sand bodies during accumulation period.
