Abstract: Analysis of drilling results and geological data from drilling production wells has shown that new information changed the initial presentation of the geological structure of the operational portion of the field under study. In accordance with the project documentation for the development of the deposits of the Tyumen Suite we identified two production zones: layers J2-4 and layers J5-6. Zones with changed geological certainty proved to be of more complex structure. The productive beds are in some cases completely washed away, which prevents the movement of fluid along the strike in the process of development. The most tectonically active and relatively stable zones within which mining is done differently have been selected within the study area. The fluid moves along the bedding within a relatively stable zone. In the tectonically active zone, stub zones are formed where the movement of the fluid is restricted or none at all. In this connection it is necessary to perform a comprehensive analysis of the geological structure of production zones with production and injection wells, controlling reservoir pressure in the development process. The results obtained have showed that the documentation for development require adjustments, and it is necessary to develop measures to regulate the development of these zones. The research was conducted within the framework of the geological model of the operational portion of the deposit.
