Zakirov T.R., Galeev A.A. Absolute permeability calculations in micro-computed tomography models of sandstones by Navier-Stokes and lattice Boltzmann equations // International Journal of Heat and Mass Transfer. – 2019. – Vol. 129. – PP. 415 – 426. |
| Аннотация |
This paper investigates the calculation features of sandstones absolute permeability coefficients on their
digital images using the lattice Boltzmann equations (LBE) and Navier-Stokes equations (NSE). The main
attention in this work is given to comparison of numerical solutions of NSE and LBE, and to study the
effects of grid refinement and grid coarsening on the calculated permeability coefficient. 3D digital
images of sandstones were obtained using X-ray computed tomography. The permeability coefficients
were calculated in sandstone samples from Imperial College London open library as well as from
Ashalchinskoe (Tatarstan, Russia) and Vostochno-Birlinskoe (Ulyanovsk region, Russia) oil fields. When
using LBE, a multi-relaxation time collision operator was applied. It was shown that permeability coefficients,
calculated using LBE, of original digital images are 20–30% higher than when using NSE. The study
of grid refinement was performed at the refinement levels ranges from 2 to 10. I |
