基于地质-地球物理资料和最新的油气勘探成果，应用石油地质综合研究方法和成藏组合快速分析技术，研究了黎凡特盆地的油气成藏特征，划分了成藏组合并分析了其成藏模式，探讨了盆地未来的勘探方向。盆地经历裂谷期、被动大陆边缘期、构造反转期3期构造演化。以中新统、上新统和中生界储层为核心，划分为3套成藏组合。中新统成藏组合最重要，渐新统-中新统生物成因气、古尼罗河大型水系盆底扇浊积砂岩优质储层、构造反转期形成的大型构造圈闭和墨西拿阶盐岩区域盖层的良好配置是油气富集的关键；上新统成藏组合表现为中小型海底峡谷水道浊积砂岩控藏，油气近源成藏；以白垩系碎屑岩及侏罗系生物礁潜在储层为核心，推测深水区发育中生界成藏组合。三者为未来重点勘探方向，深水区中新统和深层中生界是最有潜力的领域。

This paper analyzes hydrocarbon accumulation conditions, defines hydrocarbon plays and discusses their hydrocarbon accumulation models using geological and geophysical data and an international petroleum exploration and production database, with an approach of integrated geological investigation and play quick analysis. The intention is to identify favorable areas for exploration in the Levant Basin which experienced three main tectonic evolution stages, including rifting, passive continental marginal and tectonic inversion. It can be divided into three plays in Miocene, Pliocene and Mesozoic reservoirs. The Miocene play is the most important. The controlling factors of Miocene play are Oligocene-Miocene biogenic gas, high-quality submarine fan turbidite sand reservoir that related to Palaeo-Nile drainage system, large-scale anticline traps formed during tectonic inversion and Messinian evaporite as a regional caprock. High-quality channel turbidite sand reservoirs related to small-medium sized submarine canyons and short-distance gas migration are key factors that control hydrocarbon accumulation of the Pliocene play. Potential Cretaceous deepwater clastics and Jurassic carbonate build-ups on highs comprise a speculative Mesozoic play in deep water. Three plays are favorable regimes for future exploration, and the Miocene play in deep water and the under-explored Mesozoic regime are of high exploration potential.
