Strike-slip faults are important hydrocarbon migration paths, and their multistage activities have different controlling effects on hydrocarbon accumulation. Reservoirs of the hard-linked zone of the strike-slip fault are the most developed, followed by those of soft-linked segments, with translational sections of the strike-slip fault being relatively undeveloped. The segmentation of strike-slip faults strongly controls the quality of fractured vuggy reservoirs. The faults showed features of layered deformation and staged evolution in the vertical direction. The results showed that the deep strike-slip fault system, mostly distributed in the Dengying Formation, can be divided into four stages, three levels, and three groups of orientation, which controlled the structural framework and shape of the central Sichuan area, as well as the zoning from north to south, and blocking from west to east. Using a comprehensive analysis technique to assess the strike-slip fault tectonic activity history, the formation and evolution processes of strike-slip faults and their control on hydrocarbon distribution were examined. In this study, the spectral decomposition coherence method was used to describe the geometric and kinematic characteristics of these strike-slip faults. Previous studies have suggested a developed series of high-angle strike-slip fault systems in the central Sichuan Basin, but correlated exploration activities are limited, as distribution rules and dynamic mechanisms remain unclear. Deep faults research has also attracted increasing attention, as faulting plays an important role in reservoir control. The past decade has witnessed a breakthrough in the gas exploration of deep marine carbonates of the central Sichuan Basin. 3Oil and Gas Resources Strategic Research Center of the Ministry of Natural Resources, Beijing, China. 2College of Earth and Planetary Sciences, University of Chinese Academy of Sciences, Beijing, China.1State Key Laboratory of Lithospheric Evolution, Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing, China.Shangzi Liang 1,2 Zhong Li 1,2* Wang Zhang 1 Yang Gao 3
