摘　　要：特低渗均质型五里湾长6油藏进入中高含水开发阶段后,平面上水驱波及半径增大,剩余油分布复杂,剖面上注入沿高渗层段突进、低渗层段难动用,常规的注采调控技术手段挖潜难度大。针对油藏进入高含水期如何稳产及提高最终采收率的核心技术难点,本文在深入剖析开发矛盾基础上,立足一次井网水驱,通过对聚合物微球驱的矿场实践及应用效果总结,形成了较为成熟和完善的提高采收率技术,对同类油藏高含水期稳油控水具有较强的技术借鉴指导意义。After the extra-low permeability homogeneous Wuliwan Chang 6 reservoir entered the development stage of medium and high water cut, the sweep radius of water drive on the plane increased, the distribution of remaining oil was complex, injection on the section broke through the high-permeability interval and the low-permeability interval was difficult to use,and the conventional injection and production control technology was difficult to exploit potential. For oil reservoir entered high water cut period how to stable and improve the ultimate recovery of core technical difficulties, in this paper, on the basis of in-depth development of contradiction, based on a pattern of water flooding, through field practices of polymer microspheres and the application effects of the summary, formed a relatively mature and perfect to improve oil recovery technology, for similar oil reservoir with high water cut period steady water control has stronger technical guidance significance for reference.
