摘要(Abstract)：

为研究含油气盆地与下部储盖组合同源的上部储盖组合的油气聚集规律，在上部储盖组合油气成藏机制及其与下部储盖组合油气之间的关系研究的基础上，通过含油气盆地与下部同源的上部储盖组合典型油气藏解剖，利用上部储盖组合油气分布与下部储盖组合油气分布之间关系的实例分析，研究下部储盖组合对上部同源储盖组合油气聚集的控制作用。结果表明：下部储盖组合盖层渗漏区分布控制着上部同源储盖组合油气聚集区分布，下部储盖组合盖层渗漏区范围越大，越有利于向上部储盖组合供给油气和聚集成藏，反之则不利于上部储盖组合油气聚集成藏；下部储盖组合油气供给有利部位——断穿盖层油源断裂分布控制着上部同源储盖组合油气运聚成藏有利部位分布，断穿盖层油源断裂越发育，越有利向上部储盖组合供给油气和聚集成藏，反之则不利于上部储盖组合聚集成藏；下部储盖组合油气供给量控制着上部储盖组合油气成藏规模，下部储盖组合油气供给量越大，上部储盖组合油气聚集规模越大，反之上部储盖组合油气聚集规模小。研究结果对油气勘探具重要指导意义。
In order to study hydrocarbon accumulating law of upper reservoir-seal assemblage homologous to lower part of a petroliferous basin,controlling effect of lower reservoir-seal assemblage on upper homologous reservoirseal assemblage is studied based on studies of hydrocarbon accumulating mechanism of upper assemblage and its relationship with lower assemblage,through analysis on typical hydrocarbon reservoirs of upper assemblage homologous to lower assemblage and through case study of relationship between upper and lower assemblage hydrocarbon distributions. The results show that leak area distribution of lower assemblage seal controls hydrocarbon accumulation distribution of upper homologous assemblage. The larger the leakage area is,the more favorable it is for hydrocarbon supply and accumulation to upper assemblage,and vice versa. Favorable position of hydrocarbon supply in lower reservoir-seal assemblage i.e. distribution of oil source faults through caprock controls favorable position distribution of hydrocarbon migration and accumulation in upper homologous assemblage. The more developed the oil source faults are,the more favorable they are for hydrocarbon supply and accumulation to upper assemblage,and vice versa. Hydrocarbon supply amount of lower assemblage controls hydrocarbon accumulation scale of upper assemblage. The more hydrocarbon is supplied from lower assemblage,the more hydrocarbon is enriched in upper assemblage,and vice versa. The research has guiding significance for oil and gas exploration.
