Abstract: To discuss the problem that the analysis of interior architectural structures of underground fluvial reservoirs is difficult, and the heterogeneity is serious. Based on cores, outcrop, drilling and well log data, this paper analyzes the fluvial characteristics of the 3 Sand Sets in the 2 member of Shahejie Formation(S32) in 2 District, Shengtuo Oilfield(TDSO), and recognizes all kinds of hierarchical bounding surfaces, lithofacies and architectural elements in the sandbody according to Miall's suggestion. Then the paper analyzes well logs of the architectural elements, and extracts characteristic parameters, to establish quantitative fuzzy digital model and develop a set of effective software to discriminate the types of architectural elements, and the results coincide very well with the interpretation of the geological specialist. Finally, geological models are established by using this software in Shengtuo Oilfield, and this method provides scientific foundation for enhancing oil recovery in mature oilfield.
