摘要
Through the fine analysis of sedimentary facies,the microfacies 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.
