摘　　要：著名的中东油气富集区主要包括扎格罗斯前陆盆地和阿拉伯大陆边缘盆地。油气富集区内油气系统、油气藏、储盖组合、成藏组合众多,垂向叠置,分布广泛。论文去繁从简,总结了中东油气区两大主要盆地、3类圈闭类型、四大构造单元、4套主要储盖组合、五套总油气系统的基本特征。据此,划分了中东油气富集区多套成藏组合,主要成藏组合有古生界、侏罗系、白垩系和第三系成藏组合。进而以成藏组合为单元,分析了中东油气富集区各成藏组合特征、分布范围、勘探潜力和方向等。中东未来勘探领域和方向包括扎格罗斯前陆盆地低勘探程度区和深层侏罗系、古生界、阿拉伯大陆边缘盆地中沙特南部和伊拉克西部深层古生界以及低孔渗碳酸岩成藏带等。The hydrocarbon enriched area of the Middle East is mostly located in Zagros Foreland Basin and Arabian Continental Margin Basin. Many petroleum systems, plays and reservoirs are formed and extensively distributed in vertical and horizontal in this area. This paper simplifies and summarizes the general geological characteristics of this area. There are two types of basins, three types of structures, four sub-basins, four main source-reservoir-cap assemblages and five total petroleum systems. Accordingly, the hydrocarbon enriched area is divided into 16 general plays including Paleozoic, Jurassic, Cretaceous and Tertiary plays in four sub-basins. The characteristics, distribution and exploration potential of the key plays are studied and analyzed. Finally, the favorable exploration prospects are predicted, which include areas with low degree exploration in Zagros fold belt, Jurassic and more deeper zones in Zagros fold and Mesopotamia foreland, Paleozoic reservoirs in Saudi Arabia and western Iraq, and the low porosity and permeability carbonate reservoirs in the Middle East.
