FIELD: geology.
SUBSTANCE: invention relates to methods for multiscale modeling of nonlinear processes of underground hydrodynamics. Essence: break the investigated geological structure into large-scale blocks (LSB). Divide LSB into small-scale blocks (SSB). Physical property values for SSB are calculated. Values of the physical properties for the LSB are calculated with allowance for the additional correction terms of the equations, the coefficients for which are obtained from the calculations for SSB. In this case, the instability at the front of displacement of the hydrocarbon from the formation is determined as the physical property determined at SSB.
EFFECT: increase the accuracy of calculations and reduce the time of their conduct.
