摘　　要：针对新疆M油藏注水开发过程中水驱波及系数低,洗油效率差,油井见水快、含水率高的问题,提出了化学驱提高目标油藏原油采收率的对策。根据油藏特征优选出了聚合物驱、表面活性剂/聚合物(SP)二元驱、碱/表面活性剂/聚合物(ASP)三元驱三种驱替配方,通过物理模拟实验评价驱油体系。结果表明:二元驱提高采收率幅度最高,为17.43%,二元驱配方为M油藏化学驱最优体系。Aiming at the problems of low water flooding sweeping coefficient,poor oil washing efficiency,fast water breakthrough and high water cut in the water injection development process of Xinjiang M reservoir,a chemical flooding strategy is proposed to improve the oil recovery of the target reservoir.According to the characteristics of the reservoir,three flooding fluids,namely polymer flooding,surfactant/polymer(SP)binary flooding,and alkaline/surfactant/polymer(ASP)ternary flooding,are selected.The flooding is evaluated through physical simulation experiments.Oil system.The results show that the enhanced oil recovery rate of binary flooding is the highest at 17.43%,and the binary flooding formula is the optimal system for chemical flooding in the M reservoir.
