Gel Placement in Porous Media. Part 1. Constant Injection Rate. Modelling,211 Analysis and Simulation

摘要

In this paper we analyse advective transport of polymers, crosslinkers and gel,211u001etaking into account non-equilibrium gelation, gel adsorption and crosslinker 211u001eprecipitation. In absence of diffusion/dispersion the resulting model consists of 211u001ehyperbolic transport-reaction equations. These equations are studies in several 211u001esteps using mainly analytical techniques. For simple cases, we obtain explicit 211u001etraveling wave solutions, whereas for more complicated cases we rely on 211u001eanalytical techniques to analyse the problem qualitatively. Finally, a numerical 211u001esolution for the full system of equations is obtained. The results developed in 211u001ethis study can be used to validate numerical solutions obtained from commercial 211u001esimulators.
