摘　　要：聚合物驱是比较复杂的系统工程,只有在影响聚合物效果的各种油藏条件处于合理的范围内,才能取得理想的聚合物驱效果。我国东部油田大多数属于陆相沉积稠油油藏,油层渗透率较高,非均质性比较严重,原油粘度较高,这些是聚合物驱成功与否的关键油藏条件。在对国内外已实施聚合物驱的油藏技术条件研究基础上,归纳总结了聚合物驱的油藏筛选一般标准;针对陆相沉积、常规稠油油藏条件,采用数值模拟研究手段,重点对储层性质、原油粘度、注入时机等关键油藏条件对陆相沉积稠油油藏聚合物驱的开发指标进行了研究,研究结果可为类似陆相沉积稠油油藏实施聚合物驱提供指导和借鉴。Polymer flooding was a very complex system engineering;it needed each factor being at the favorable level to achieve ideal oil displacement effect of polymer flooding.Most of the oilfields in Eastern China were generally continental deposition reservoirs.These reservoirs were characterized by features such as high permeability,strong heterogeneity;high oil viscosity,these reservoir conditions were key to the success of EOR in polymer flooding on the basis of the reservoir polymer flooding techniques used both at home and abroad,the reservoir criteria of polymer flooding were presented.By numerical simulation techniques,the key reservoir technology conditions to polymer flooding are studied for the continental deposit heavy oil reservoir,including reservoir permeability,heterogeneity,oil viscosity,polymer injection time,etc.These study results can provide reference for the similar conventional heavy reservoir polymer flooding.
