【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。
[Abstract]:Based on the geological and seismic data of the Levant basin in the eastern Mediterranean, the prototype basin and lithofacies paleogeography of the main geological periods were restored, the basin structural characteristics were compared and analyzed, and the reservoir forming model was established by combining the dissection of the discovered gas reservoirs. The favorable reservoir forming assemblage in this area and the exploration direction in the next step are discussed. The Livant basin is mainly composed of three stages: early fault, middle fault and late fault. The early faults were mainly controlled by intracontinental faults, and the deep water areas in the southern part of the basin were less affected by late compressive stress, while the intermediate faults were mainly affected by lateral tectonic stress and the Syrian arc fold belt, and the tectonic activity gradually weakened from north to south, from east to west. The late faults are well developed due to collision and compression and the Dead Sea strike-slip fault zone, but they are not pierced through the thick layer evaporite of the upper Miocene. Combined with the discovery of oil and gas reservoirs and outcrops, it is considered that Mesozoic sandstone, carbonate rock, Cenozoic carbonate rock and Temmar sandstone near Elatoseney uplift on the far shore of Israel are the next major exploration directions.
