针对聚合物驱后油藏缺乏有效提高采收率接替技术的问题，研发了新型非均相聚合物驱油剂PPG产品。
PPG as a new type of immiscible polymer flooding system was studied for the purpose of enhancing the oil recovery of after polymer flooding reservoirs.
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%.
而注表面活性剂和聚合物的复配体系段塞后热水驱虽然提高采收率幅度较大，但吨油新增成本较高，经济上不合理。
The surfactant and polymer mixed system slug is well on recovery ratio but the additional cost of ton oil is higher, economic benefit is not satisfactory.
