| 摘 要： | 油气运聚单元是盆地中被油气运移分割槽所围限的具有相似油气运移和聚集特征的独立和完整的三维石油地质单元。油气运聚单元主要根据盆地油气运移聚集特征来划分,油气运聚单元的边界是流体势高势面所确定的油气运移分割槽或在油气运移过程中起分割作用的其它地质体,如大断裂等。油气运聚单元的分析内容主要包括有效烃源岩的规模及其演化历史、油气输导体系类型和分布、圈闭的类型及其有效性以及运移聚集特征,它们是决定运聚单元油气资源丰度的主要因素。油气运聚单元分析可以比油气系统分析对勘探目标做出更直接的评价,可以作为油气勘探的直接依据。

| Abstract: | Petroleum migration and accumulation unit(MAU) was an independent and complete 3 D petroleum geological unit with same petroleum migration and accumulation features, which was confined by high fluid potential interface, large fault or lithological or diagenetic belt. MAU was recognized according to petroleum migration or accumulation features, with the boundary of MAU being a high fluid potential interface, large fault and lithological or diagenetic belt. The analysis and assessment of MAU was mostly emphasized on hydrocarbon generation amount and history, type and distribution of petroleum conductive system, type and effectiveness of traps and the features of petroleum migration, which were main elements controlling the abundance of petroleum resources in MAU. Therefore, the MAU analysis could give out more direct assessment on petroleum prospect than petroleum system analysis, and the result of MAU analysis could be directly used in petroleum exploration. |
