摘要：

流动单元模型是油藏数值模拟的基础,基于流动单元的层次性,建立流动单元模型可分5步来完成:(1)取芯井段流动单元划分;(2)未取芯井段流动单元划分;(3)建筑结构模型的建立;(4)建立参数模型;(5)形成流动单元模型。对双河油田的研究表明,该区可划分出极好型、好型、一般型和差型4种流动单元。极好型流动单元具有最好的储层物性,主要存在于分流河道和河口坝砂体中,而差型流动单元则有最差的物性,主要位于席状砂体中。地层系数是决定流动单元的最主要的因素,对于未取芯井,可以用这个参数来进行流动单元的划分。

Abstract:

Flow unit model is the premise of reservoir numerical simulation.According to the reservoir properties,the model can be founded through five steps as following:①divide and determine cored-well flow units;②divide and determine the uncored-well flow units;③found reservoir architectural model;④found parameter model;⑤found flow unit models.According to the study made in Shuanghe Oilfield,Henan Province,four types of flow units as E,G,F,P were recognized,within which type E has perfect reservoir property and is distributed in distributary channels and river mouth bars;type P has the poorest property and is distributed in sheet sandbodies.It is proposed that formation factor is the main factor in determining the flow units,and could be used in dividing the flow units of uncored wells.
