| 摘 要： | 塔里木盆地塔中低凸起是中央隆起带的一个次级构造单元,可分为塔中1号断裂构造带、塔中北坡及中央断垒带3个构造单元.作为一个长期发育的继承性隆起,其构造演化经历了7个阶段.多次隆升和沉降也造就了多套有利储盖组合,形成了丰富的、多种类型的圈闭;多期区域性不整合面和区域性大断裂的发育也为油气运移聚集提供了优良场所和通道.塔中地区是油气运聚、富集的有利地区.奥陶系圈闭具有近水楼台先得月的优势,形成了多个油气藏.塔中1号断裂构造带是最为有利的油气聚集区,塔中北坡次之,中央断垒带最差.塔中1号断裂带依然是下一步勘探的重中之重.

| Abstract: | The Tazhong (middle Tarim Basin) Low Arch is one of the sub-tectonic units of middle harimUplift. It is composed of the Tzl fault zone, the Tz north slope and the middle fault-horst zone.The razhong Low Arch is a long-term successive rise which has experienced 7 periods of evolution. The multi-period rising and subsiding brought up lots of reserve-seal assemblages and abundant traps.The multi-period regional unconformities and major faults provided excellent pathways and locations for petroleum migration and accumulation.The Tazhong Low Arch is favorable for petroleum migration and accumulation.The ordovician system has many petroleum reservoirs in a favorable position.The Tzl fault tectonic zone is the most favorable zone for petroleum accumulation with the Tz north slope as the second and the middle fault-horst zone as the worst.The Tzl fault tectonic zone is still the favorable prospect of future exploration. |
