N2 - We propose a microscale model of the main structural element ("bearing" layers) of kerogen-clay-carbonate-siliceous rocks of the Bazhenov formation. The model treats the rock as a composite material with inorganic clay matrix and different content of organic inclusions (up to 25%) and micropores filled with low-viscous fluid (light hydrocarbon fractions). A computer simulation of the mechanical behavior of representative samples of structural elements of the studied rock under triaxial compression was carried out using the hybrid cellular automaton method and a coupled mechanical model that takes into account the mutual influence of porous rock deformation and filtration of a pore fluid. It is shown that the mechanical behavior of the "bearing" layer of rock at side pressures that meet the characteristic conditions of occurrence is satisfactorily described by rock plasticity models with two-parameter flow functions.
