摘　　要：为了提高裂缝性油藏水驱后的采收率,将聚合物微球的封堵作用和表面活性剂的驱油作用相结合,提出了一种适合裂缝性油藏水窜水淹储层的高效调驱驱油技术。室内评价了表面活性剂BMY-11和聚合物微球JHWQ-3的各项性能,复合调控驱油技术的驱油效果。试验结果表明:表面活性剂BMY-11能够显著降低油水界面张力值,具有良好的耐温性能、抗盐性能及乳化性能。聚合物微球JHWQ-3具有良好的膨胀性能,对不同渗透率的岩心均能达到良好的封堵效果。裂缝性岩心水驱后注入聚合物微球-表面活性剂复合调控驱油体系可以有效提高原油采收率,能够满足裂缝性油藏水窜水淹储层提高采收率的需求。In order to improve the recovery of fractured reservoirs after water flooding,a high efficiency profile control and displacement technology suitable for fractured reservoirs with water channeling and flooding is proposed by combining the plugging effect of polymer microspheres with the oil displacement effect of surfactant.The performances of surfactant BMY-11 and polymer microspheres JHWQ-3 are evaluated in laboratory,and then the oil displacement effect of composite control flooding technology is evaluated.The results show that the surfactant BMY-11 can significantly reduce the oil-water interfacial tension,which show good interfacial activity in high temperature and high salt reservoir.In addition,the surfactant BMY-11 also has good emulsification.The polymer microsphere JHWQ-3 has good expansion performance,which can achieve good plugging effect for cores with different permeability.After water flooding in fractured cores,injection of polymer microspheres surfactant composite control flooding system can effectively improve the oil recovery,which can meet the needs of water channeling and flooding in fractured reservoirs.
