摘要
根据岩心和测井资料并利用模糊聚类方法 ,对胜坨油田二区沙二段 83 层三角洲相储集层特点进行了研究。研究结果表明 ,将该区三角洲储集层流动单元分为 4种类型 ,并从岩性、物性、电性、微观和空间分布、非均质及水淹特征等方面分析了每类流动单元的特点 ,建立了流动单元模式。 4种流动单元的宏观、微观及空间分布规律是 ,在垂向上受沉积韵律控制 ,在平面上受沉积相带分布控制。流动单元与剩余油的形成及分布有关 ,将剩余油的形成与流动单元结合起来研究 ,可以更好地预测剩余油分布 。
The flow unit is helpful to set up a three-dimensional geological model for imaging reservoir heterogeneity and can directly predict the distribution of remaining oil. The reservoir characteristics of delta reservoir in layer 83 of the second block in Shahejie Formation of Shengtuo Oilfield were investigated using a lot of data from core and log. The flow units of this reservoir were divided into four types using the fuzzy clustering method. The characteristics of lithology, physical property, electrical character, heterogeneity, space distribution and water-flooding features, specialty and laws of four types of flow units were analyzed, and the correspondent modes of flow units were set up. The distribution characteristics of these flow units were controlled by sedimentary rhythm in vertical direction, and those were controlled by facies distribution in plane. The flow units controlled the distribution and modes of remaining oil. It is important to combine the study of the distribution laws of remaining oil with the study of the distribution laws of flow units. In this way, the remaining oil distribution can be correctly predicted.
