ZG Gas Field is located in Sumatra Basin of Indonesia with complex segments and multiple of depositional systems. Based on the background of deposition and clastic reservoir type, logging sedimentary facies study method is used toidentifydeposition facies byanalyzingthe characteristics oflogseries includingGR, SP, RLLD and DEN, combined with core, master log, seismic data, sequence stratigraphy, etc. The rocks-electrical switching models of core phase are established. Fan delta, braided delta and lake deposition facies are identified and different loggingmicrofacies characters models of depositional facies are obtained. Analyzed and recognized fan delta-braided delta-lake depositional system was developed in Lower Lumut zone, braided delta-lake depositional system was developed in Middle Lumut zone and delta front-shallow lake depositional system braided was developed in Upper Lumut zone by studying characters of microfacies distribution. Braided delta distributary channel sand body is favorable reservoir.
