| 摘 要： | 古生界是中东地区重要的天然气和轻质原油勘探层系,阿拉伯板块构造--沉积演化为古生界油气聚集成藏提供了有利的石油地质条件。分析认为,前寒武纪—寒武纪早期Huqf群和志留纪Qusaiba段两套优质成熟的烃源岩、多套有利的储盖组合以及一系列大型基底隆起或盐拱成因背斜、断背斜圈闭控制着古生界油气的分布,构成了古生界Huqf和Qusaiba两套主要的含油气系统,每套含油气系统均包括多个油气成藏组合。受早期继承性古隆起和盐构造、有利储盖组合以及断裂通道3个主控因素的影响,古生界油气成藏以下生上储侧向+垂向断裂输导运聚成藏模式为主。

| Abstract: | The Paleozoic layes are important for natural gas and light oil exploration in Middle East． Tectonic and sedimentary evolution of Arabian Plate provided favorable petroleum conditions for Paleozoic hydrocarbon accu- mulation． The analysis shows that two sets of high-quality mature source rocks in Precambrian-lower Cambrian Huqf Group and Silurian Qusaiba Member，accompanied with multiple sets of favorable reservoir-cap assemblage as well as a series of large scale anticlines and faulted anticlines traps induced by basement uplift or salt-arch controlled the Paleozoic hydrocarbon distribution． Huqf and Qusaiba are the two main petroleum systems in Paleozoic section，and each petroleum system includes several oil and gas plays． Affected by the three main controlling factors of the inher- ited palaeo-high and salt structure，the favorable reservoir-cap assemblages and the fault passageway，the predomi- nant hydrocarbon accumulation model is migration and accumulation based on transportation through lateral and ver- tical fault and a“generated in the lower and stored in the upper part”． |
