Annotation:
The article, on the example of the Middle Jurassic deposits of the well-studied territory of the Tevlinsko-Ruskinskiy field, a methodology for predicting probable transition and accumulation zones of fragmental material of continental sediments is proposed for further use as an additional parameter during complex geological interpretation of seismic data. The methodology is based on the principles of paleotectonic, paleogeomorphological analysis and geomorphometry (analysis of relief digital models). The general patterns of the territory evolution during the formation of the deposits of the Tyumen formation are determined. The use of hydrological modeling in the territory under consideration provided construction of a model of the probable distribution zones of paleochannels in the Middle Jurassic age. Based on the analysis of the results obtained, the methodology was refined, after which the forecast model was adjusted. The author’s model of probable zones of fragmental material transition and accumulation was compared with the model obtained within the framework of seismic solutions. Promising directions of the developed methodology practical application with the purpose of further development of the work were identified.
