摘要
流动单元是具有相同渗流特征的岩相组合 ,应用该方法可以精细刻划储层的非均质性。针对新疆克拉玛依油田八区克上组砾岩油藏储层非均质性严重的特点 ,利用八区克上组取心井岩心分析资料 ,计算FZI、RQI、ΦZ、ΦR 等参数 ,采用Q型聚类分析方法将该区砾岩储集层划分为 5类流动单元 ,并分别分析、描述了各类流动单元的地质特征。
A flow unit is a combination of lithological units with similar hydraulic features. Using this concept, the heterogeneity of a reservoir can be depicted subtly. There exists serious heterogeneity in conglomerate reservoir of Keshang member in the Area 8 of Karamay oilfield. According to the characteristics of the conglomerate reservoirs, four parameters including F Z I, R Q I, Φ Z, and Φ R are computed from core data of this area. The reservoir is then divided into five flow units by Q-type cluster analysis. Geological properties of each flow unit are analyzed.
