Abstract
The possible occurrence of convection in fine-grained (low-porous <15%) fluid-saturated (argon, water) rocks under hydrostatic pressures of up to 100 MPa is studied. Calculations of the Rayleigh filtration number and the Darcy number are presented. It is shown that the convective motion of fluid does not occur in pore-saturating fluids within the considered range of pressure variation, pore sizes, and temperature differences.
