摘　　要：针对准噶尔盆地层阜东斜坡区储层影响因素多、评价难度大、储层研究薄弱这一现状,以阜东斜坡区侏罗系头屯河组为例,分析研究区样品岩石学特征及物性特征。首先,分析岩心资料,建立测井孔隙度物性解释模型。优选孔隙度、含泥率、泥岩厚度、微相类型、含砂/砾率、砂岩厚度作为储层评价因素,建立阜东斜坡侏罗系头屯河组储层评价模型。运用灰色系统理论选定母子序列并计算出关联系数和关联度,进而得到评价参数的权系数;采用拐点法确定储层综合评价的分类阈值,明确储层分类标准,实现对阜东斜坡区侏罗系头屯河组储层评价。经生产测试验证,评价结果与油气实际产能具有很好的一致性,表明基于孔隙模型和灰色理论的储层表征评价方法切实有效。In view of the present situation of many influencing factors,difficult evaluation and weak reservoir research in Fudong slope area of Junggar Basin,the Jurassic Toutunhe Formation in Fudong slope area is taken as an example to analyze the petrological and physical characteristics of samples in the study area.Firstly,analyze core data and establish a logging porosity physical property interpretation model.The porosity,mud content,mudstone thickness,microfacies type,sand/gravel ratio and sandstone thickness are selected as reservoir evaluation factors,and the reservoir evaluation model of Jurassic Toutunhe Formation in Fudong slope is established.The grey system theory is used to select the mother-child sequence and calculate the correlation coefficient and correlation degree,and then the weight coefficient of the evaluation parameters is obtained.The inflection point method is used to determine the classification threshold of reservoir comprehensive evaluation,and the reservoir classification standard is clarified to realize the reservoir evaluation of Jurassic Toutunhe Formation in Fudong slope area.The production test shows that the evaluation results are in good agreement with the actual productivity of oil and gas,indicating that the reservoir characterization evaluation method based on pore model and grey theory is effective.
