模拟油在岩心中的自发乳化驱采收率和总采收率分别为24.5%和71.8%，与超低界面张力聚合物表面活性剂驱相近。
The simulated oil spontaneous emulsification flooding recovery and total recovery with cores are enhanced by 24.5% and 71.8%.
实验结果表明，在聚合物总用量相同的情况下，随着高分子量聚合物浓度的增大，聚合物驱采收率增大。
The experimental results show that, under the condition of the same total amount of polymer, polymer flooding recovery will increase with the increase of high molecular weight polymer concentration.
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；
The recovery of the layer with high permeability is higher than the lower one; however, it has little effect on the total recovery.
