| 摘 要： | 通过岩心、录井、测井等资料综合研究，分析了阿尔及利亚438b区块三叠系Serie Inferiere段的辫状河沉积特征。采用熵权法，综合考虑孔隙度、砂岩密度、渗透率突进系数、渗透率变异系数、渗透率级差和夹层频率等6种影响储层非均质性的因素．计算了研究区三叠系Serie Inferiere段储层平面非均质综合指数，并在沉积相约束下，绘制了储层平面非均质性展布图。该方法充分利用熵权法的弱化和强化，即去同存异的特点．较准确地表征了研究区储层的非均质性。 |

| Abstract: | Based on the analysis of core, logging and drilling, the sedimentary characteristics of braided channel in Serie Inferiere of Triassic in 438b block are analyzed. Combined with porosity, sand density, onrush coefficient, variation coefficient, permeability graded difference and frequency-interlayers, the entropy weight method is used to calculate the heterogeneous synthetic index in Serie Inferiere of Triassic. The distribution map of reservoir heterogeneity is drawn based on sedimentary facies. This method can take fully advantages of entropy weight method, and it can accurately characterize the horizontal heterogeneity. |
