摘　　要：针对渤海油田高效开发面临的技术需求,以提高采收率为目标,利用现代物理模拟方法,对六种新型驱油剂的流动性能和驱油效果进行了评价。结果表明,六种驱油剂中,泡沫复合体系的流动性能和驱油效果最好,其次为二元复合体系和PA-2聚合物溶液,PA-1聚合物溶液和"PA-1聚合物+ES微球"体系较差。聚合物驱后进一步提高采收率增油效果较差。Facing the technology demand of BoHai oilfield development,aiming at improve the recovery target and using the modern physical simulation,the flow properties and flooding effects of six new oil displacement agent have been evaluated.The results show that the flow properties and flooding effects of foam compound system is the best,improve the recovery 26.1% relative to water flooding,second,the surfactant/polymer compound system and the PA-2 polymer,improve the recovery 19.3% and 17.6%,the 'PA-1polymer+ES mesospheric' system is the worst,improve the recovery only 14.0% and 11.7%.The EOR Technology after Polymer Flooding is poor,improve the recovery only 2.8% relative to polymer flooding.
