摘　　要：通过精细沉积相研究,统计了各小层微相比例,将萨尔图油田北三西区按沉积微相构成分为4种储层结构类型,即以河道相为主的A类、B类,以前缘席状砂为主的C类、D类。利用地质约束建模方法建立地质模型,以小层为单元,计算了不同微相的储量,并对储量分布进行了统计分析,表明不同相结构储层中的储量分布不同,其储量结构各异在传统储量评价的标准上,考虑相结构对储量控制的因素,由评价结果认为,该方法能比较直观地表达出不同成因砂体的储量,为后期分析不同砂体的挖潜潜力提供定量化的依据。Through the fine analysis of sedimentary facies, the microfaeies proportion of different sand bodies is analyzed. The reservoirs in Beisanxi Area of Saertu Oilfield are divided into four reservoir structures： Type A and Type B, which are mainly distributary channel facies; Type C and Type D, which are mainly sheet sand of delta front. The geologic model is established using the geologic constrain modeling method. In a small layer for unit, the reserves of different microfacies are calculated and reserves distributions are analyzed, which shows that the reserves distribution of reservoir with different facies structure have different features and the reserves structures are different. On basis of traditional reserves estimation and considering the influence factors of facies structure on reserves control, this paper also considers that this method can directly represent the reserves of different genetic sand bodies and can provide a quantitative basis for analyzing the potentialities of different sand bodies.
