摘要
两亲聚合物以其良好的增黏能力和乳化性能,在油田提高采收率领域逐步开展应用。本文首先从提高波及系数和洗油效率两方面总结了两亲聚合物的提高采收率机理,其次从油藏条件和两亲聚合物注入参数两方面分析了两亲聚合物提高采收率效果的影响因素,最后探讨了三大类两亲聚合物增效体系的提高采收率潜力。研究成果可为矿场两亲聚合物提高采收率效果评价预测以及矿场方案设计提供指导。
Amphiphilic polymers,with their excellent thickening and emulsifying properties,have been gradually applied in the field of enhanced oil recovery.The mechanism of enhanced oil recovery by amphiphilic polymers was summarized from the aspects of enhancing sweep efficiency and displacement efficiency.The recovery efficiency of amphiphilic polymers under different injection modes was investigated,including injection slug size and injection timing.Finally,the potential of enhanced oil recovery for the three types of synergistic systems was discussed.The research results could provide guidance for the evaluation and prediction of the recovery efficiency of amphiphilic polymers in the oilfield.
