摘要(Abstract)：
为了研究聚驱中、后期利用井网加密方式改善油层发育和连通较差区块的聚合物驱开发效果的可行性,在室内采用大型平面物理模型开展了聚驱中、后期井网加密物理模拟实验。实验结果表明,聚驱中、后期利用井网加密可以进一步改善聚驱开发效果,且加密时机越早越好。
Physical simulation experiments about well pattern infilling during middle-later polymer flooding stages are launched adopting the indoor large-scale planar physical model,in order to analyze the feasibility of improving polymer flooding effect on reservoir development and poorer blocks connectivity through the way of well pattern infilling during middle-later polymer flooding stages.Results obtained from the experiments indicate that well pattern infilling during middle-later polymer flooding stages will improve the polymer flooding effect,and the earlier of the infilling time the better.
