摘　　要：针对注水开发油田剩余油的挖潜问题,首先对注水开发油田剩余油分布及挖潜技术研究现状进行分析,对剩余油的分布特征进行探讨,对剩余油的挖潜技术进行深入研究,为推动我国注水开发油田的进一步发展奠定基础。研究表明:对于注水开发油田而言,其剩余油的分布主要呈现出窄条带状以及孤岛状的基本特征,因此,在进行开发的过程中需要采取相应的措施,在进行剩余油挖潜的过程中,需要从重复压裂技术、压裂配套技术角度出发,分别采取多项有效措施,进而使得剩余油挖潜效果可以得到一定的改善。Aiming at tapping the potential of remaining oil in water injection development oilfield,this research first analyzes the distribution of remaining oil in water injection development oilfield and the research status of tapping potential technology,discusses the distribution characteristics of remaining oil,and conducts in-depth research on tapping potential technology of remaining oil,which lays a foundation for promoting the further development of water injection development oilfield in China.The research shows that for water injection development oilfield,the distribution of remaining oil mainly presents the basic characteristics of narrow strip and island.Therefore,corresponding measures should be taken in the process of development.In the process of tapping the potential of remaining oil,multiple effective measures should be taken from the perspectives of refracturing technology and fracturing supporting technology,so that the effect of tapping the potential of remaining oil can be improved to a certain extent.
