| 摘 要： | 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。通过长岩芯驱替实验考察了PPG产品的运移能力；利用微观物理模型对比了聚合物驱后油藏条件下二元驱与PPG驱的驱油效果。结果表明，聚合物驱后再用PPG驱波及能力最强，聚合物驱后再用二元驱的洗油效率高。将两种体系叠加，配制PPG与聚合物及表面活性剂形成的非均相复合驱油体系，在聚合物驱后再用非均相复合驱油体系驱可进一步提高采收率达10％以上。

| Abstract: | 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.The migration ability of the PPG system was evaluated by means of long core displacement experiment.Both polymer-surfactant-combination flooding and PPG flooding were investigated via utilizing the microscopic physical model.The experimental results indicated that PPG flooding after polymer flooding was more efficient in increasing the sweep volumes,and that ... |
