The prediction of post-fracturing production in horizontal wells is crucial for designing effective hydraulic fracturing parameters in tight shale reservoirs. However, conventional production prediction methods face significant challenges in utilizing conventional well logging data due to the substantial heterogeneity and variation in reservoir lithology and properties in both vertical and horizontal directions. To overcome these challenges, researchers have primarily used analytical and numerical simulation methods to study the production capacity of horizontal wells in tight shale formations. Additionally, some scholars have attempted to study the fracturing production of tight shale horizontal wells using methods such as hydraulic simulation and linear regression. However, the application scope of physical simulation methods based on hydroelectric similarity theory is limited and not suitable for low-permeability and ultra-low-permeability oil and gas reservoirs. Furthermore, research on regression empirical models, numerical models, and analytical models regarding the impact of strong heterogeneity and complex reservoir spatial types in tight fractured sandstone and tight conglomerate formations under the existence of natural fractures is still relatively limited.
