摘要

The search for the optimal development of a field involves proper knowledge of fluids compositions that impregnate reservoirs. Therefore, we performed a study of therodiffusion phenomenon in a forced convective flow, permanent, dynamically and thermically established. The equations were solved with a spectral method and we calculated the evolution of the mass fraction in a two components within a Periodic geometry representative of a pore. Evaluation of the effect of different parameters on the composition were achieved in order to understand the complex phenomena which Takes place at geological time scale and to obtain the effective local thermodiffusion coefficients, which take local heterogeneities into account for a simulation at larger scale.
