Abstract:
In the oil fields of Western Siberia, the average water cut has reached ۸۰-۹۵%, with a relatively low oil recovery factor (RF) of ۳۸%. This paper proposes a comprehensive approach to solving the problem of water encroachment: identifying the cause of water cut, selecting a flow deviation technology (FDT) and its composition, selecting an affected area (isolating a zone), and calculating technological and economic efficiency. To determine the reason for the high water cut in a producing well, the Chan’s graph-analytical method was used. The FDT and chemical composition were selected based on the geological and physical characteristics of the production facility. The justification of the site for conducting the FDT was based on calculations and construction of the map of residual recoverable reserves of oil using the software package "RN-KIN". The assessment of technological efficiency was conducted according to the KogalymNIPIneft method and by building a hydrodynamic model using the modelling software tNavigator.
