چکیده
|
To study an oil reservoir, the first step is to determine its fluid composition in both horizontal and vertical directions. in this research, oil composition variation is investigated as a result of diffusion and natural convection in a fractured porous medium. a single-phase binary mixture and a rectangular two-dimensional fractured model with a known temperature profile are used. governing equations are solved by matlab software, numerically. according to the results, thermal diffusion has the greatest impact on the variation of fluid composition, followed by pressure and molecular diffusions, respectively. moreover, it is understood that even a small convection would change the fluid composition distribution, considerably. fluids tend to flow through the fracture due to its high permeability; therefore, a counterclockwise convective cell forms in the porous medium.
