三角洲沉积储层非均质性强，储层内部渗流特征复杂，制约了油藏的高效开发。以大庆油田 W区块葡 I 油层组为例，考虑影响流体流动的微观孔隙结构特征，利用4个储集物性参数，采用聚类分析方法，定量划分 W 区块葡 I 油层组为5类独立的流动单元，通过确定流动单元内的孔隙度与渗透率相关性，对各流动单元建立测井解释模型。结果表明，孔隙度、渗透率曲线与岩心资料吻合率大幅度提高。

Delta sedimentary reservoir heterogeneity has strong internal,complex flow characteristics of the reservoir,so it restricts reservoir efficient development.Take daqing oilfield block z portuguese oil group I as an example,considering the impact of microscopic pore structure characteristics of fluid flow and use four reservoir physical parameters.The cluster a-nalysis method is used to divided into five separate categories flow units.Then by determining the flow correlation between porosity and permeability within the unit,build logging interpretation model for each flow unit.The results show that the porosity and permeability curves are consistent with core data rate.
