A series of experiments were carried out to study the dynamic and static adsorption capacity of Cr~(3+) polymer gel,its influence factors and mechanism by means of instrument detection.The results indicated that the higher concentration of polymer and crosslinker,the lower core permeability is,as well as the greater amount of dynamic adsorption of Cr~(3+) polymers,which causes the injection pressure to rise,meaning that resistance factor and residual resistance factor increase.Thus,the adjustable polymer concentration range and crosslinking agent concentration range are both revealed.
