摘要: 针对测井储层评价中的渗透率预测问题,基于相控建模理念,采用流动单元分析法,将所研究工区划分为4个特征明显的流动单元;采用最能表征储层储集性能的声波时差、补偿密度、补偿中子、自然伽马、流动层带指数进行模糊聚类分析,选取最大隶属度大于70%的最优样本进行建模,得到流动单元的判别模型;建立了复杂砂砾岩储层渗透率模型,提高了储层流体渗透性能的预测精度,为非均质储层物性认识提供了参考方法。

Abstract: In view of permeability prediction in well logging reservoir evaluation,based on the idea of facies-controlled modeling,the flow unit analysis is carried out to group the unit,in the study area,four apparently characterized flow units are identified.The fuzzy cluster analysis is conducted by using AC,DEN,CNL,GR and flow zone index which can best characterized accumulation property of reservoir,modeling is implemented by selecting the optimal samples with maximum membership degree being greater than 70%,identifying model of flow unit is obtained.The permeability model of complex glutinite reservoir is set up,prediction accuracy of reservoir fluid permeability is improved.The recognition provides reference for understanding heterogeneous reservoir physical property.

Key words: heterogeneous reservoir, glutinite, flow unit, permeability prediction, fuzzy cluster analysis
