摘　　要：塔里木盆地深部流体活动的2个必要因素是火山岩浆作用和深大断裂发育。前者是深部流体形成的基础,后者为深部流体从深部向浅部运移提供通道。塔里木盆地塔中和巴楚地区二叠系火山岩广泛发育,在塔中的中1井附近区域和巴楚的吐木休克断裂、色力布亚断裂、康塔库木断裂以及玛扎塔格断裂区域是火山岩浆活动的中心区域。塔中的塔中Ⅰ号、塔中10井、塔中Ⅱ号等断裂和巴楚地区的吐木休克断裂、色力布亚断裂、康塔库木断裂、玛扎塔格断裂等在海西晚期是活动的,可作为深部流体活动的有效断裂。塔中和巴楚地区具有二叠纪火山岩浆活跃区域并且存在有效断裂发育区域,因此,既是深部流体活跃的区域,也是深部流体对下古生界碳酸盐岩储层溶蚀改造的有利区域。Volcanic activities and deep faults caused deep fluid activities in the Tarim Basin.Volcanic activities gave birth to deep fluids,and deep faults provided pathways for deep fluids to migrate upwards.In the middle Tarim and Bachu regions,Permian volcanic rocks were widespread.Around well Zhong1 of the middle Tarim region and in faults such as Tumuxiuke,Selibuya,Kangtakumu and Mazhatage of Bachu region,volcanic activities were the most active.During the late Hercynian,the faults Tazhong Ⅰ,Tazhong well 10 and Tazhong Ⅱ in the middle Tarim region and the faults Tumuxiuke,Selibuya,Kangtakumu and Mazhatage in Bachu region were active faults for deep fluid activities.In this way,the middle Tarim and Bachu regions with active deep fluid were favorable for carbonate reservoir corrosion in the lower Paleozoic.
