摘要： 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 stratified (including 5 structural layers), and also segmented, with the southern and northern segments demonstrating different kinematic characteristics. The former has experienced 5 stages of evolution, and the latter has experienced 4 stages of evolution.

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 stratified (including 5 structural layers), and also segmented, with the southern and northern segments demonstrating different kinematic characteristics. The former has experienced 5 stages of evolution, and the latter has experienced 4 stages of evolution.
