摘要: 综合地质、地球化学、地球物理资料,划分和评价了渤海湾盆地北部某凹陷的油气运聚单元。渤海湾盆地研究区共划分为深、浅两个成藏动力学系统,并应用层次分析法从生排烃、储集、运聚和保存4个方面对该凹陷两个成藏动力学系统的油气运聚单元进行了综合评价,结果浅层成藏系统中的5号运聚单元成藏条件最好;深层成藏系统中的5号运聚单元成藏条件最好,2号、3号运聚单元次之。

Abstract: According to the data of geology, geochemistry and geophysics, the migration and accumulation units of a sag in northern Bohai Bay Basin are divided and assessed. There are two reservoir formation dynamic systems in the Bohai Bay Basin. The analytical hierarchy process is used to assess the migration and accumulation units of the two dynamic systems from the four aspects of hydrocarbon generation and expulsion, accumulation, migration and preservation. The result shows that No.5 unit in the shallow dynamic system has the best hydrocarbon accumulation; No.5 unit in the deep dynamic system has the best hydrocarbon accumulation, while No.2 and No.3 units take the second place

Key words: analytic hierarchy process, migration and accumulation unit, assessment of migration and accumulation unit, exploration target
