摘　　要：储层岩石物理相（ＲｅｓｅｒｖｏｉｒＰｅｔｒｏｐｈｙｉｃａｌＦａｃｉｅｓ）是沉积作用，成岩作用和后期构造改造等作用的综合反映。同一岩性相可对应于不同的岩石物理相。本文根据孔隙结构特征参数，孔隙度，渗透率，泥质含量，粒度中值等５项参数，采用模糊优化综合评价方法，将大庆油田北部储层划分为５类岩石物理相。阐述了各类岩石物理相的主要特征，并根据测井相初步划分为三个级别。Reservoir Petrophysical Facies is defined as the combined results of deposition, diagenesis, later tectonism and so on.The same lithofacies corresponds to the different petrophysical facieses.According to the following five parameters:pore structural characteristics, porosity, perm eability, mud content and median grain size and by comprehensive fuzzy optimization evaluation method,the reservoir petrophysical facies in the northern part of Daqing Oilfield can be divided into five types.The paper describes the main characteristics of each petrophysical facies and generally classifies these five facies into three grades by the log facies.
