摘要: 为了研究提高高含水油藏采收率技术方法,从提高采收率基本理论人手,简析了驱油效率、剩余油饱和度、毛细管数、调剖驱油剂等主要影响因素;根据采收率的构造要素,结合淮城油田沙一下油藏特点,确定并采用了降低油水界面张力为主的吞吐法与堵水法相结合新的技术方法,该技术通过增加毛细管数、降低剩余油饱和度、提高驱油效率,从而提高采收率.经现场实验,该技术措施适用,增油降水效果显著,值得借鉴.

关键词: 高含水油藏, 采收率, 驱油效率, 毛细管数, 界面张力, 驱油剂

Abstract: In order to improve recovery efficiency of high water-cut reservoir, the paper analyses main affecting factars of oil displacement effieiency,remaining oil saturation,capillary canstant,etc,from basic theory of recovery efficiency. Based on the components consisting of recovery efficiency,and combined with reservoir characteristics in the formation of Low Est, Pucheng Oilfield, it decides to adopt new techniques of reducing oil-water interfacial tension and water shutoff. Recovery efficiency is to be enhanced by increasing capillary constants, reducing remaining oil saturation and improving oil displacement efficiency. Having been put into application, the technology is effective and practical.

Key words: high water-cut reservoir, recovery efficiency, oil displacement efficiency, capillary constant, interfacial tension, oil displacement agent
