<p>Based on the interpretation results of 3D seismic data, integrated with drilling and production dynamic data, this study focuses on the Shunbei 8 strike-slip fault zone in the Tarim Basin. It determines the spatial distribution, activity intensity, and evolutionary process of the fault, and explores the differential control mechanisms of different overlapping segments and activity intensities on reservoir development and hydrocarbon distribution. The results indicate that: The Shunbei 8 strike-slip fault zone can be divided into three segments in the plane according to its strike: north, middle, and south. According to the fault mechanics mechanism, it can be divided into 10 uplift segments, 14 pull-apart segments, and 9 strike-slip segments, with significant differences in the structural patterns of each segment. In the vertical direction, it exhibits layered deformation characteristics at deep, intermediate, and shallow levels. Fault activity primarily occurred in four stages from the early Caledonian to the middle to late Hercynian periods. The middle Caledonian Stage III was the main period for the formation of the main fault, while the middle to late Hercynian period had the highest activity intensity, exhibiting a “weak central, strong lateral” characteristic. The intensity of fault activity is closely related to reservoir development. High-intensity activity can form a dense fracture network, promoting reservoir development and hydrocarbon accumulation. The study also found that oil and gas production in the Shunbei 8 zone exhibits the characteristic of “less in the south and more in the north.” High-yield wells are concentrated in the overstepping segment in the northern section, and the uplift segment has better reservoir development than the pull-apart segment and strike-slip segment. High-intensity activity in the late stage of the fault helps the development of fractures and cavities, which has a constructive effect on the Ordovician carbonate reservoir.</p>
