| 摘 要： | 多参数识别是流动单元研究的发展方向，判别参数选择是多参数识别流动单元的关键。以鄂尔多斯盆地L37井区延安组Y9段河流相储层为例，应用SPSS统计分析软件，通过对表征储层的六项属性参数判别流动单元的能力及参数之间的相关性分析，选取粒度中值、孔隙度、流动层分层指数三项参数作为L37井区流动单元判别参数，建立了流动单元判别函数，研究了储层非均质特征。研究表明，本区的河流相储层可以划分为为Ⅰ、Ⅱ、Ⅲ、Ⅳ四类流动单元，分别分布在曲流砂坝、决口扇和砂坝顶部、天然堤微相中，层内非均质性表现为夹心型、均变型、均质型三种类型。针对不同的储层非均质性，油田开发生产中应采取不同的开发对策。

| Abstract: | Selecting discretion parameter is the key of multi parameters to identify flow units. Taking reservoir of fluvial facies in the area of Well L37 in Ordos basin as an example, utilizing SPSS statistical analysis software, through analyzing the discretions and their connection between six parameters of reservoirs, the discretion function of flow units has been established, the characters of flow units and heterogeneities of reservoirs have been investigated. There are four types of flow units and three kinds of intrastratal heterogeneities, the flow units ofⅠ,Ⅱ,Ⅲ,Ⅳ distributes in sedimentary microfacies of point bar, crevasse, natural levee. Different measures should be adopted according to the characters of reservoir heterogeneities. |
