目前水驱仍是高含水、高采出程度即“双高”油田的主要开采方式。分析了近年来深部液流转向与调驱的技术进展及存在的问题，认为有必要强化针对深部液流转向与调驱的油藏基础理论研究，攻关水流优势通道分布定量描述技术，实现对高含水后期存在水流优势通道油藏渗流规律的合理描述。另一方面，从工艺、材料等诸方面着力解决堵剂的“有效深部放置”问题。此外，加快试验应用在线注入设备，满足深部液流转向与调驱技术规模化、同步化的需要。

Water flooding remains a main production mode in ‘double-high’ (high water cut and high percentage of reserve recovery) oilfields. After the recent progress and problems of deep fluid diversion and profile control technique were analyzed, some suggestions were proposed. Firstly, it is necessary to further study the basic oil reservoir theories in relation to deep fluid diversion and profile control and work on the quantitative description technology for dominant water path distribution, so as to characterize the seepage laws of oil reservoir with dominant water paths at the late stage of high water cut development. Secondly, innovative ideas should be held to ensure the “effective deep placement” of plugging agent from the aspects of technique and materials. And lastly, online injection equipment test and application should be accelerate, so as to realize intensive and synchronous development of deep fluid diversion and profile control technique.
