摘　　要：物理模拟是研究非均质油藏油水两相渗流规律的重要手段,其理论基础即相似准则。基于相似理论和方程分析法,考虑流体粘滞力、毛管力和重力,推导出注采井定压和定产条件下非均质油藏水驱油三维物理模拟相似准则。针对微尺度管流存在的摩阻效应,提出了井径等价处理方法,保证了模型与原型的全面相似关系。基于相似准则和井径等价处理方法建立的实验模型,可对油藏开发过程进行定量物理模拟。Physical simulation,whose theoretical base is similarity criteria,is an important method for researches on two phase flow laws in heterogeneous reservoirs. With using equation analysis and taking into account viscous force,capillary pressure and gravity,the similarity criteria of 3D physical simulation about two phase flow in heterogeneous reservoirs,when the injection-production pressure difference and the well flow rate are constants respectively,are developed according to similarity theory. Equivalent process of the well radius is present to solve the well-bore friction problem which exists in micro well radius. Then the similarity between the model and the reservoir is achieved. The lab model which is established based on the similarity criteria and the well radius equivalent process method can simulate the reservoir performance quantitatively.
