对喇嘛甸油田北东块聚合物驱已见效的抽油机井示功图形状、载荷变化及与此有关的产油量变化进行了初步的分析，取得了初步认识，丰富了聚合物驱评价资料，使试井资料这一成果为聚合物驱的工作者全面分析评价聚合物驱油提供了经验，为今后进一步开展聚合物驱采油提供了实践依据。
Preliminary analysis has been carried out on the dynamometer shape and load change of oil well drilled in North East Block polymer flooding in Lamadian Oilfield and the change of oil yield related to this. The preliminary understanding has been obtained and the evaluation data of polymer flooding have been enriched The results of the well testing data provide the polymer flooding practitioner with a comprehensive analysis of polymer flooding experience and provide a practical basis for further carrying out polymer flooding in the future.
