摘　　要：河南油田目前三次采油的主体是二类储量单元,针对二类储量单元采出程度高、综合含水高、聚驱见效迟缓的现状,开展了以提高二类储量聚合物驱见效比例、见效厚度、见效倍数为目的的聚合物驱动态调整技术研究,寻求促进单元整体见效及特高含水区域见效的技术对策,形成了改善聚合物驱效果的过程控制"六项技术":合理配液配注技术、边水控制技术、浓度差异调整技术、聚窜控制技术、期封堵高含水层评价动用技术、聚驱适度提液技术。六项调整技术在现场实践中应用效果显著,对其它同类单元的开发可提供经验借鉴。The main body of tertiary oil recovery in Henan oilfield is type Ⅱ reserves, which is characterized by high recovery degree, high integral water cut and low efficiency of polymer flooding. In order to change the present situation, dynamic adjustment technology aiming at enhancing efficiency, thickness and scale has been carried out. Therefore, six countermeasures to improve development effect of type II reserves have been established, namely reasonable liquid supply and filling system technology, edge water control technology, concentration variation adjustment technology, channeling technology, sealing high water cut layers evaluation technology and lifting fluid technology. The application of these technologies has obvious effect and can provide experienced guidance for the development of others of the similar kinds.
