摘要(Abstract)：

聚合物相对分子质量既是描述聚合物特性的重要参数,也是影响聚驱效果的重要参数。与主力油层相比,大庆油田中、低渗透率油层物性及发育状况均发生很大变化,如果仍沿用主力油层聚驱的聚合物相对分子质量确定方法,必将会对聚合物相对分子质量的选择造成很大的误差。本文从聚合物相对分子质量对聚驱采收率提高值的影响和对聚驱控制程度的影响两方面入手,提出了一种新的、定量化优选适合油层条件聚合物相对分子质量的方法,为指导聚合物驱技术的矿场应用提供了新的手段。
Molecular weight is an important parameter for not only describing polymer property but also influencing polymer flooding effect. The reservoir property and development status of medium-low permeable reservoirs in Daqing Oil Field are different from the major reservoirs. Using the determination method of polymer in major reservoirs will have much error for polymer selection. This paper proposes a new quantitative method for optimizing suitable polymer according to the effect of polymer on incremental recovery value and polymer controlled degree so as to provide evidence for field application.
