本文利用热采数值模拟手段和回归分析方法研究了油层厚度、原油粘度、含油饱和度、渗透率变异系数、油层净总厚度比和油藏埋深等主要油藏参数对蒸汽驱开发效果的影响，并且得到了蒸汽驱开发采收率与诸油藏参数之间的关系式，作出了它们之间的关系曲线。在此基础上，进一步得到了不同稠油油藏蒸汽驱采收率的预测公式。通过国内外几个蒸汽驱先导试验的实例证明了所得预测公式的有效性。
In this paper, the effect of main reservoir parameters on the development of steam flooding was studied by means of numerical simulation of thermal recovery and regression analysis methods, such as reservoir thickness, crude oil viscosity, oil saturation, coefficient of variation of permeability, net total thickness ratio of reservoir and reservoir depth , And got the relationship between the recovery of steam flooding recovery and reservoir parameters, and made the relationship curve between them. On this basis, the prediction formula of steam flooding recovery of different heavy oil reservoirs is further obtained. Several examples of steam flooding pilot tests at home and abroad have proved the effectiveness of the predictive formula.
