三维按比例油藏物理模型的几何尺寸、时间间隔、注蒸汽速率、地层孔隙度、渗透率、油饱和度、蒸汽的温度、压力和油的粘度等参数与相应油田原型的参数是按比例模拟的。本文的模拟方法有几个特点：１）在冷油带和蒸汽带，用两个不同的相似准则来确定油的粘度；２）模型初始参数的选择，利用最小二乘法概念，用计算程序进行最优化；３）所用相似准则可以兼顾油层吸热和向盖、底层导热两个方面，并可以用单一直径的玻璃珠来模拟油藏岩石。
Parameters such as geometry, time interval, steam injection rate, formation porosity, permeability, oil saturation, steam temperature, pressure and viscosity of the oil in the 3D proportional-proportional reservoir physical model are proportionally simulated with those of the corresponding field prototype of. The simulation method in this paper has several features: 1) The viscosity of the oil is determined using two different similarity criteria in the cold oil zone and the steam zone. 2) The selection of the initial parameters of the model, using the concept of least squares, is performed using a computational program Optimization; 3) The similar criteria used can take into account both the heat absorption of the oil layer and the thermal conductivity of the cover and the bottom layer, and can simulate the reservoir rock with single-diameter glass beads.
