摘　　要：基于文献调研,从聚驱后水淹层地质参数变化规律及机理、测井响应变化规律及机理、水淹级别划分及测井识别方法、储层参数测井定量评价方法 4个方面介绍了聚驱后水淹层测井评价方法的研究现状.研究认为,目前按照常规水淹层的模式开展聚驱后水淹层测井评价的技术方法总体是合适的,但需要加强聚驱后电测井机理实验方法研究,特别是要加强水淹层电阻率与产水率、含水饱和度、混合液电阻率的实验联测方法和实验规律分析工作.同时,考虑到储层的非均质性,建议在细分地质单元、注聚受效分析等地质、工程约束下开展聚驱后水淹级别测并识别和定量评价方法研究.This paper presents the current research status of water-flooded zones after polymer flooding on the basis of literature research on the change law and mechanism of geological parameters, the change law and mechanism of logging response, classification and recognition of the flooded strata and the quantitative evaluation of the parameters. It shows that it is generally suitable to use the conventional methods to evaluate the water-flooded zones after polymer flooding. However, it is necessary to strengthen the research on experimental methods, especially on the simultaneous measurements and analysis of flooded zones, water productivity, water saturation and mixed liquid resistivity. Meanwhile, it is recommended to classify and evaluate the water flooded degree based on the detailed classification of geological units and analysis of the effects under the geological and engineering guidance because of the strong anisotropy of the formation.
