【摘要】 按大、中、微三种尺度逐层次精细剖析了赵石窑曲流河道砂体的内部构成及储集层非均质性特征.在峭壁断面写实基础上,观测了砂体的空间几何形态、成因相类型、特征及相互配置关系;识别划分了六级界面、十二种储集层岩性相、四种隔挡层,并研究了它们的沉积及分布特征,为建立定量的储集层地质模型提供了重要依据.更多还原

【Abstract】 This paper dissected the configuration and reservoir heterogeneity characteristics in meandering channel sandbody in Zhaoshiyao on the scale of macroscope, mesoscope and microscope.Based on the realistical description of the cliff and the observation of space geometric shape, types and characteristics of genetic facies and their interrelation of sandbody, six levels of interfaces, twelve types of reservoir lithofacies and four types of barrier beds were distinguished, their sedimentation and distribution characteristics were studied. Hence an important basis for developing the quantitative reservoir model is provided.更多还原
