塔里木盆地顺北5号走滑断裂带分层分段特征及构造演化

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。

Stratification and Segmentation Characteristics and Tectonic Evolution of Shunbei No.5 Strike-Slip Fault Zone in Tarim Basin

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.
