摘要
///Based on the regional geological data, the distribution characteristics, index and type of sedimentary microfacies of the sand groupⅤof the upper Sha-3 Member in Jie Faulted Block 2 of Linnan Oilfield were studied systematically by means of core observation, lithofacies and log facies analysis. The results showed that the sand groupⅤof the upper Sha-3 Member in Jie Faulted Block 2 of Linnan Oilfield was a lake delta sedimentary system, parfacies type was delta front. The sedimentary microfacies of the sand groupⅤwas divided into underwater distributary channel, underwater interdistributary bay, mouth bar, distal bar and front sheet sand, and the corresponding recognition modes were built. The characteristics and plane distribution of sedimentary microfacies were that the continuity of sand body was fine in east-western profile, mouth bar and front sheet sand were alternate, and sand body horizontally transited from underwater distributary channel to mouth bar or front sheet sand in southeast-northwestern profile.
