| 摘 要： | 利用试验方法对HPAM溶液在不同渗透率岩心上的注入能力进行研究,基于试验结果建立聚合物驱附加阻力与岩心渗透率的相关关系,并在此基础上建立考虑聚合物注入附加阻力效应的油藏数值模拟模型.模拟结果表明:低渗岩心中注入聚合物时稳定注入压力增大,即确实存在附加阻力效应;聚合物注入附加阻力对聚合物驱效果预测有较大影响,考虑聚合物注入附加阻力,聚合物起效时间早、含水率下降幅度减小、聚合物有效期变长.

| Abstract: | The injection properties of HPAM polymer solution on cores with different permeability were studied by experiments.And a correlation of additional resistance of polymer flow with the core permeability was established based on the experimental results.And a numerical reservoir simulation model of polymer flooding was established considering the influence of additional resistance.The results show that the injection pressure increases when the polymer is injected into low-permeability cores,which indicates the... |
