摘　　要：流动单元指一个受砂体及其内部因受边界限制、不连续薄隔挡层、各种沉积微相界面、小断层及渗流率差异等造成的渗流特征相同、水淹特征一致的储层单元。本文以渤海湾盆地某油田为例,综合考虑沉积环境、储层宏观特征、储层微观孔隙结构与流体流动特征等参数,对研究区储层进行流动单元识别与划分,通过参数优选后,选择与水淹程度相关性较好的岩相类型、泥质含量、渗透率、流动带指数与电阻率下降率作为识别参数,主要分为4类静态流动单元,不同类型流动单元具有不同的水淹特征,由于河道砂体整体呈现正韵律,在河道下部往往发育物性较好的Ⅰ类静态流动单元。Flow unit refers to an oil sand body and its internal reservoir unit with the same seepage characteristics and consistent water flooding characteristics caused by boundary restrictions,discontinuous thin barrier layer,various sedimentary microphase interfaces,small faults and differences in seepage rates.This paper takes an oil field in Bohai Bay Basin as an example,comprehensively considering the depositional environment,reservoir macroscopic characteristics,reservoir microporous structure and fluid flow characteristics and other parameters,the reservoir in the study area for the identification and division of flow units,through the parameter preference,the selection of the degree of correlation with the degree of waterflooding of the lithological type,mud content,permeability,flow zone index and resistivity decline rate as the identification of the parameter,is mainly divided into four types of static Different types of flow units have different flooding characteristics,and because the river sand body as a whole shows a positive rhythm,the lower part of the river channel tends to develop Class I static flow units with better physical properties.
