Abstract The Luzhou shale gas block,which is located in the southern Sichuan Basin,has undergone multi-stage tectonic evolution and has complex faults and multiple sets of vertical detachment layers,forming the characteristics of multiple stages,multiple strikes,and multiple layers.To overcome the difficulties with the tectonic interpretation of the study area,this study combined a set of seismic multi-attribute techniques,namely using seismic multi-attribute optimization and attribute fusion technique to assist fault interpretation,using structural anomaly attribute to identify microstructures,using seismic attribute slicing technique to analyze the characteristics of tectonic temporal and spatial evolution,and using multi-superposition ant tracking attribute technique to predict fracture development.Using this technique combination,this study completed the fine-scale interpretation of complex faults in the area, effectively characterized the development of microstructures,clarified the tectonic stages and distribution in the area,improved the fracture prediction accuracy,and described the development characteristics of fractures.The results of this study will provide solid data and a foundation for the next platform deployment.
