摘要: 为进一步提高海上油田二元复合驱后油藏采收率,针对二元驱后油藏特点及存在的开发矛盾,结合室内物理模拟实验,在常规驱油剂的基础上设计3种不同组合方式的驱油体系,提出了高浓聚合物驱、高浓聚合物+二元及非均相3种提高采收率方案并进行了实验对比。结果表明,3种实验方案均出现不同程度的含水率二次下降、高渗层分流率减小、中低渗层分流率增加现象,提高采收率分别为13.55%、10.93%和16.05%,为后续调剖优化和单井个性化设计提供了技术支持,为完成一套二元驱后进一步提高采收率技术方法体系奠定基础。

Abstract: In order to further improve the recovery of oil after binary composite flooding in offshore oil fields,based on the development contradiction existing after the binary flooding,combined with the indoor physical simulation experiment,three different combinations of oil displacement systems were designed on the basis of conventional oil displacement agents. According to the characteristics of the reservoir after the binary flooding,three kinds of high concentration polymer flooding,high concentration polymer + two yuan and heterogeneous phase were proposed and compared with the experiment. The results showed that the three experimental schemes showed different degrees of secondary decline in water,the shunt rate of the high permeability layer decreased,and the shunt rate of the medium and low permeability layer increased.The recovery rate of experiment was 13.55%,10.93% and 16.05%,respectively.It provides technical support for subsequent profile optimization and individual well personalized design,which lays the foundation for the completion of a set of recovery technology method system after a set of two yuan flooding.

Key words: Offshore oil field, Binary composite flooding, Orthogonal experiment, Shunt rate, Enhanced oil recovery
