| 摘 要： | 针对洪积扇相储层沉积厚度大、储集岩性粗、非均质性强等特点,提出了以地质研究为主线,定性分析与定量分析相结合的分层次流动单元研究方法。基于流动单元的定义及其地质内涵,根据FZI直方图和累积频率曲线作图法,对取心样品进行定性分析,以此作为流动单元定量判别的依据,同时辅以物性、岩性、孔隙结构等表征流动单元的定量指标建立流动单元定量识别模式,最后应用随机建模方法对流动单元进行井间预测。研究结果表明,应用该方法划分流动单元,精细表征了厚层砾岩储层的强非均质性特征,与油田开发动态特征具有较高的吻合度,取得了较好效果。

| Abstract: | In order to improve the depiction of reservoir heterogeneity of thick proluvial fan reservoir,a novel method for classifying flow units is presented.Based on FZI histogram and FZI cumulative frequency curves of cored well samples,three types of flow units can be recognized qualitatively,which are the basis for discriminating flow units quantitatively.Then,Integrating parameters of reservoir quality,lithology and pore structure into the cluster and discrimination analysis,a quantitative model is deve-loped to define flow units in uncored but logged wells.Finally,by use of stochastic modeling method,the distribution of flow units between wells is simulated,which honors the reservoir geology reasonably and accords with production well performance properly.The results show that this method is applicable and very effective to reveal the heterogeneous characteristics of thick proluvial fan reservoir. |
