摘　　要：文中利用盆地流线模拟结果对渤海湾盆地南堡凹陷油气运聚单元进行了精细刻画,使用层次分析法,对研究区各油气运聚单元内不同类型输导体系的输导性能进行了定量评价。结果表明:研究区源上油气藏细分为9个油气运聚单元,源内及源下油气藏细分为11个油气运聚单元。20个油气运聚单元输导的油气中,断层输导的油气为52%,砂体输导的油气为36%,不整合面输导的油气为12%,源内和源下油气藏具有较大的勘探潜力。研究区不同构造带输导体系的输导性能划分为4类,南堡2号构造带和南堡4号构造带输导条件较好,与现今油气勘探程度不匹配,具有较大的勘探潜力。Based on the basin modeling of streamline, hydrocarbon migration and accumulation units in Nanpu Sag of Bohaiwan Basin were finely depicted, and the transporting capability of different types of transport systems in every unit was quantitatively evaluated by the use of analytical hierarchy process. The research resuhs show that the reservoirs over source rocks were subdivided into 9 hydrocarbon migration and accumulation units, while the reservoirs in source rocks and under source rocks were subdivided into 11 units in study area. For the hydrocarbon transported by 20 units of hydrocarbon migration and accumulation, the hydrocarbon transported by fault accounts for 52%, the hydrocarbon transported by sand body takes up 36% and the hydrocarbon transported by unconformity surface is 12%. The reservoirs within source rock and under source rock have a great exploration potential. The transporting capability of transport system in different tectonic belts can be divided into 4 types. Nanpu No.2 and Nanpu No.4 tectonic belts show a good transporting condition and have a great exploration potential, which does not match the current degree of hydrocarbon exploration.
