摘　　要：本文以10区东高精三维区为基础,开展不同序次断裂及古河道系统的精细解释与识别,结合断裂和古河道空间配置,根据不同地质背景岩溶成因模式,分析研究区奥陶系储集体形成的控制因素。研究结果表明,本区断裂发育受"X"剪切应力控制,区内发育有两大古河道体系,区内岩溶储集体在覆盖区和剥蚀区的发育主控因素受断裂和古河道体系的空间配置关系影响,前者以断控岩溶为主,后者则为多因素复合控制。Based on the 3D high-precision seismic area in Eastern 10 area, the different fault sequence interpretation and the recognition of ancient river system is launched, the analysis of reservoir development controlling factors is completed. The results show that the fault development of this area is controlled by the ＂X＂ shear stress, and there are two ancient river system in this area. The main controlling factors of karst reservoir development in the area of coverage and erosion are influenced by the spatial configuration of the fault and the ancient river system, the former is mainly controlled by fault karst, and the latter is mainly controlled by multiple factors.
