| 摘 要： | 针对流动单元划分方法不断发展过程中流动层带指标法和孔喉半径r35法可能存在的弊端，通过深入研究这两种方法所表达的内在含义，发现它们都是从岩石微观孔隙结构出发，以孔喉的大小对流动单元进行分类和评价，是同一物理性质的不同表达形式。同时，由于它们只反映了储层的一个物理因素，势必导致用这两种方法划分流动单元具有局限性。从流动单元的概念出发，提出只有从连续（通）性、相似性和独立性三个方面对流动单元进行划分和评价，才能准确有效地对储层进行评价。

| Abstract: | The division methods of flow unit are constantly developing to meet the need of oil and gas field development since the concept of flow unit was put forward first,especially,the method of flowing zone index and the method of pore throat radius (r35) are the most popular ones nowadays.However,through thorough application,the two methods are not adjusted to the practice in the oilfield.Authors of this paper investigate the internal meanings of the methods and discover that the two methods which come from the microcosmic pore structure are different expression forms from one physics property to appraise the flow unit.At the same time,it is thought that only when the continuity,similarity and independence are taken into account to evaluate the flow unit,can the reservoir be evaluated effectively and correctly. |
