The sequence stratigraphic models for the clinoform part of the section in the territory studied by production drilling within the Nadym-Pur oil and gas region of Western Siberia are constructed. The purpose of study was to identify patterns in the distribution of reservoir properties of the Achimov objects and substantiate a systematic approach to the correlation of reflecting horizons. The main task is to identify the characteristic features of systemic tracts based on core data from a well-studied field. To solve the problem, a classification of sediments studied by core in wells was carried out within the framework of a sequence model. To confirm theoretical concepts about the formation of improved reservoir zones in system tracts, an analysis of filtration and capacitance parameters (porosity, permeability) was performed. There is the relationship between the reservoir properties and the type of system tract in which the deposits were formed. The seismic section requires the interpretation according to the principles of sequence stratigraphy, and criteria for tracing reflecting horizons. An algorithm for constructing a model is proposed that provides a forecast of zones with improved reservoir properties. A number of advantages for the unsystematic approach to correlating reflecting horizons are given.
