摘要
为了深化姬塬地区长6低孔低渗透储层的精细化分及评价,选取孔隙度(Φ)、渗透率(K)、有效厚度(h)、渗透率纵向变异系数和储层品质系数(RQI)这五个特征参数,利用岩性-物性划分法和多参数聚类分析法把姬塬地区长6储层划分为Ⅰ、Ⅱ、Ⅲ、Ⅳ四类流动单元。研究结果表明,粘土矿物含量及微观孔隙结构特征是决定研究区不同流动单元分类的主要影响因素,Ⅰ类、Ⅱ类好的流动单元面孔率高,粘土矿物含量相对少,溶孔发育,孔隙连通性好,渗流能力和储集能力较好,是今后进一步生产开发的主力储层。
In order to strengthen jiyuan area chang 6 low porosity and low permeability reser- voir classification and evaluation in detail, select porosity（D）, permeability（K）, the effective thickness （h）, vertical coefficient of variation and reservoir quality coefficient （RQI）these five characteristic parameters, using the method of lithology-physical property division and multi parameter clustering analyze, the chang 6 reservoir is divided into I , I], ]][, 1V four types of flow unit. The results showed that clay mineral content and microscopic pore struc- ture is the mainly influence factors of different classification of flow units in the study area. The I and ]] types of flow unit are good type,they are the characteristics of high face rate, clay mineral content is relatively small, solution pores is development, the pore connectivity, seepage ability and reserve ability is good. This flow unit type is the main production and development of reservoir in the future.
