摘　　要：蒸汽辅助重力泄油(SAGD)技术是开采稠油和油砂的重要技术,其开发效果受储层参数的影响。采用数值模拟方法研究了垂向渗透率、储层厚度、孔隙度、含油饱和度等储层参数对SAGD技术开发效果的影响。结果表明,储层厚度、孔隙度、含油饱和度与开发效果呈正相关关系。在水平渗透率一定的情况下,垂向渗透率对开发效果的影响存在最优值。对不同储层参数进行正交试验设计的结果显示,对于油汽比、采出程度、平均日产量等因变量,储层厚度、垂向渗透率、含油饱和度及孔隙度的影响程度不同。根据正交试验分析结果对稠油油藏SAGD技术开发的适应性进行量化评价,可为前期制定开发策略提供参考。The steam assisted gravity drainage （SAGD） is an important technology for the development of heavy oil and oil sands, and the development effect is influenced by reservoir parameters. The numerical simulation method has been used to study the influence of vertical permeability, reservoir thickness, porosity, oil saturation, etc. on the SAGD technology development. The results indicate that reservoir thickness, porosity and oil saturation are positively correlated with the SAGD performance, and there is an optimal value of vertical permeability on the development effect under the condition of constant horizontal permeability. The orthogonal experiment design is carried out for different reservoir parameters, and applied the variance analysis to the testing results. Taking oil vapor ratio, production level, average daily output as the dependent variables respectively, the effect of various parameters on the size of development has been compared. According to the analysis result of orthogonal experiment, the quantitativeevaluation of the applicability of SAGD in heavy oil reservoir, and provide a reference for making the development strategy in the early stage.
