To investigate the difference of shallow water delta front subfacies reservoir, Moxizhuang area, located in the central Junggar Basin, was selected. Four sedimentary microfacies combination styles, including superimposed underwater distributary channel combination, truncated underwater distributary channels combination, superimposed estuarine dam combination and upper channel and lower residual dam combination, were identified, and the typical identification marks were analyzed. The typical characteristics of reservoirs developed by different sedimentary microfacies combination styles were summarized in combination with hydrodynamic index, physical property parameters and thin sections. The results indicate that the shallow water delta front subfacies mainly develop superimposed underwater distributary channel combination, truncated underwater distributary channels combination, while the development of superimposed estuarine dam combination and upper channel and lower residual dam combination is relatively limited. Superimposed underwater distributary channel combination and superimposed estuarine dam combination are mainly formed under relatively weak hydrodynamic conditions, while truncated underwater distributary channels combination and upper channel and lower residual dam combination are mainly formed under strong hydrodynamic conditions. The reservoir developed by superimposed underwater distributary channel combination type is dominated by sandstone deposition with good sorting, developed rigid debris, weak cementation, strong dissolution, high porosity and permeability, and weak reservoir heterogeneity. It is the most favorable reservoir type of shallow water delta front subfacies.
