ABSTRACT
In order to evaluate percolation ability of aqueous dispersion system of nano/micron-sized polymer particles in porous media, the flow characteristic and its influence factors were studied by laser particle size analyzer and filtration device of microporous membranes which were simulated to reservoir pore throat. The results show that at the same hydration time, plugging capacities of nano/micron-sized polymer particles gradually increase as their average particle sizes increase; at the different hydration time, plugging capacities of nano/micron-sized polymer particles show a trend of increasing first and then decreasing with increasing average particle sizes. With increasing pressure differentials, the plugging capacities of nano/micron-sized polymer particles gradually decrease and their deep profile control capacities gradually increase. When pore sizes of microporous membrane decrease, the plugging capacities of nano/micron-sized polymer particles rapidly increase and their deep profile control capacities quickly decrease. When the particle concentrations increase, the plugging capacities of nano/micron-sized polymer particles increase and their deep profile control capacities decrease.
