Abstract: Under this condition of asp flooding, in order to Seriously, it will blocking reservoir pore, reduce the sweep
determine the scale of asp flooding position, to efficiency of oil displacement agent, damage the reservoir
investigate scaling mechanism, we take experimental area's scale effect and ultimately affect recovery factor. Therefore, we
