随着我国对石油的需求量不断增加,对油气田的进一步挖潜显得至关重要。化学驱技术是提高采收率的重要技术之一,而聚合物驱作为最主要的化学驱提高采收率方法,在矿场上已经得到了广泛应用,并取得良好的驱油效果。该文通过对聚合物驱的基本原理以及各种驱油用聚合物的发展现状进行综述,对聚合物驱的矿场应用效果进行总结,展望了聚合物驱在高温高盐等苛刻油藏环境下的发展方向。通过综述可以看出,虽然耐温抗盐共聚物、速溶聚合物、两亲聚合物等功能型聚合物已成功研发,但应用于矿场的聚合物类型仍然有限,如何将新型聚合物的研发成果应用于现场提高采收率是重点发展方向。随着不同聚合物类型的研发,对聚合物驱油机理的研究需要继续深入。

With the increasing oil demand in China, it is very important to further tap the potential of oil and gas fields. Chemical flooding technology is one of the important technologies of EOR, and polymer flooding, as the most important method of EOR, has been widely used in the field and achieved good oil displacement effects. Therefore, by summarizing the basic principles of polymer flooding, the development status of various kinds of polymer for oil displacement and the field application effect of polymer flooding, the development direction of polymer flooding in harsh reservoir conditions, such as high temperature and high salt, has been prospected. Through the review, although functional polymers, such as temperature resistant and salt resistant copolymers, instant polymers and amphiphilic polymers, have been successfully developed, the types of polymers used in the field are still limited. How to apply the research and development achievements of new polymers to on-site EOR is the key development direction. With the development of different polymer types, further research on polymer flooding mechanism is needed.
