HAGS can increase oil recovery by adjusting the permeability variation through plugging the higher permeability layer and forcing the injected water to flow into the lower permeability layer.
HAGS通过封堵高渗层，调整模型的渗透率差异，使液流转向低渗层，从而达到提高采收率的目的。
The recovery of the layer with high permeability is higher than the lower one; however, it has little effect on the total recovery.
整个开采过程中高渗层采收率相对高，但对总的平均采收率影响不大；
