In order to weaken the effect of shearing， adsorption and dilution on the bulk gel， a new profile control agent（zirconium gel dispersion agent）was prepared by the mechanical shear method with zirconium gel. The main influence factors such as bulk gel strength， shear time and shear distance on the viscosity and particle size of dispersion agent were evaluated， and the plugging and profile control performance of dispersion agent was studied in laboratory. The results showed that the gelation time and gel strength of zirconium bulk gel could be controlled by adjusting the dosage of polymer and zirconium crosslinker. With increasing dosage of both polymer and crosslinker， the crosslinking rate accelerated and gel strength became stronger. The size of zirconium gel dispersion could be controlled from 5.66 to 224.87 μm by adjusting bulk gel strength， shear time and shear distance， whereas， the viscosity ranged from 1.8 to 41.0 mPa·s. With increasing bulk gel strength and shear distance， the viscosity and particle size of dispersion agent increased， while that decreased with increasing shear time. The core flooding test results showed that the plugging rate of zirconium gel dispersion decreased with increasing core permeability. The dispersion agent had an ability to control injection profile， and enhanced oil recovery rate was up to 46%.
