Abstract: The fan delta deposit in Mabei area of Junggar basin is characterized by wide distribution of glutenite reservoirs, but various types of sand bodies and unclear control factors on the reservoirs caused the difficulty of related logging evaluations. Based on the core samples’ observation, this paper studied the petrology of the core unit combination controlled by different sedimentary facies, and comprehensively analyzed the core lab and the formation test data. The results show that the rock type, sorting feature and rock cementation type are the main control factors on the glutenite reservoir development. The physical property and reservoir quality tend to become poor from the grey pebbly medium-coarse sandstone in underwater distributary channel to the brown glutenit facies in overwater braded river channel. The log characterization method for the glutenite lithology and lithofacies is as follows: a) using FMI logs to identify the rock texture and structure, and classify the microfacies of glutenite; b) using conventional logs combined with FMI logs to identify the lithology, and c) using the difference between neutron log porosity and NMR effective porosity to evaluate the shale content, sorting coefficient, etc. The case study indicates that this combination method can be applied to classification and evaluation of glutenite reservoirs
