摘要 基于东地中海黎凡特盆地地质、地震等资料,恢复主要地质时期原型盆地及岩相古地理,开展盆地构造特征对比分析,并结合已发现气藏特征解剖,建立成藏模式,探讨该区有利成藏组合及下一步勘探方向。黎凡特盆地主要发育有早期断层、中期断层和晚期断层等3期构造。早期断层主要受控于陆内断陷,盆地南部深水地区受后期挤压应力影响较小;中期断层主要受侧向构造应力和叙利亚弧型褶皱带影响,构造活动由北向南、由东向西逐渐减弱;受碰撞挤压和死海走滑断裂带影响,晚期断层十分发育,但基本未刺穿中新统上部厚层蒸发岩。结合已发现油气藏及露头情况,认为以色列远岸邻近埃拉托色尼隆起的深水地区中生界砂岩、碳酸盐岩及黎巴嫩深水地区新生界碳酸盐岩和塔马尔砂岩为下一步主要勘探方向。 By using geologic and seismic data, this study restored the proto-type basins and lithofacies paleogeography of the Levant basin in East Mediterranean during main geological periods, carried out comparison analysis on the basin architecture characteristics, and based on careful examination of the characteristics of discovered gas reservoirs, established the reservoir forming pattern and discussed the favorable reservoir forming combinations and future exploration direction in this region. Three structural architectures can be identified in the basin, the early-stage faults, the mid-stage faults and the late-stage faults. The early-stage faults are mainly controlled by intercontinental depression, which were less influenced by later compression stress in the southern deep water area of the basin. Controlled by the lateral structural stress and the Syrian Arc Fold Belt, the mid-stage faults became less active from north to south and from east to west. Influenced by the collision and/or Dead Sea strike-slip Fault Zone, the late-stage faults were active but did not pierce the thick Upper Miocene evaporites. Combined with the discovered reservoirs and outcrops, the Mesozoic sandstones and carbonates in deep water area near Eratosthenes seamount of Israel offshore and the Cenozoic carbonates and Tamar sands of Lebanon offshore are the main petroleum exploration targets in the next step.
