Annotation:
Taking into account specific features of phase permeability curves behavior (RFP hysteresis) in the hydrodynamic model (HDM) under a reservoir cyclic testing (CT) helps increasing the reliability of reservoir fluid saturation calculations as well as modeling the process of piston and non-piston effects when implementing methods of oil recovery increase. The calculation of drainage and impregnation curves, based on standard core studies data, is possible using the electrical saturation parameter according to the S.D. Pearson equation. Since the hydrodynamic model takes into account the heterogeneity of productive formations, it allows calculating the stop time (half cycle) for each injection well, based on observation hydraulic testing. Using an integrated approach to planning the implementation of the central heating zone at the expense of taking into account the hysteresis in the GDM, justifying the half-cycle of injection, and allocating areas of non-drainable reserves will allow reducing the deviation of planned and actual oil production by two times as well as contribute to additional production increase due to taking into account changes of reservoir dynamic properties.
