摘　　要：塔里木盆地超深层断溶体油气藏主要沿走滑断裂带分布,远离断裂带地区油气勘探效果差,即走滑断裂带的活动规模控制了油气藏的规模。顺北5号走滑断裂带为超大型走滑断裂带,具有埋藏深,内部结构复杂,分层分段性极强的特点。通过高品质三维地震资料,对顺北5号走滑断裂带进行系统的几何学、运动学和动力学研究,提出以下认识:顺北5号走滑断裂带具有极强的分层性,可划分为5个构造层;该断裂带分段活动特征明显,南段和北段具不同的运动学特征,南段经历了5期演化,北段经历了4期演化。The ultra-deep fault-karst reservoirs in the Tarim basin are mainly distributed along strike-slip fault zones,and the oil and gas exploration effects are poor in the areas far away from fault zones,that is,the activity scale of strike-slip fault zones control the scale of hydrocarbon accumulation. The Shunbei No.5 strike-slip fault zone is a super-large strike-slip fault zone,which is characterized by deep burial,complex internal structure,and evident stratification and segmentation. Based on high-quality 3D seismic data,the geometry,kinematics and dynamics of the Shunbei No.5 strike-slip fault zone were systematically analyzed. It is recognized that the Shunbei No.5 strike-slip fault zone is evidently layered(including 5 structural layers),and also segmented,with the southern and northern segments having different kinematic characteristics. The southern segment has experienced 5 stages of evolution,and the northern segment has experienced 4 stages of evolution.
