摘　　要：在常规稠油油藏蒸汽吞吐动态预测模型的基础上,运用能量平衡理论,建立了裂缝性稠油油藏蒸汽吞吐开采动态预测模型,给出了热膨胀作用、重力驱替和毛管渗吸作用下的分析解。在求解过程中,考虑了温度对粘度、含油饱和度和油水相对渗透率的影响。该模型的实例计算结果与数值模拟计算结果相近,这表明该模型能用于裂缝性稠油油藏蒸汽吞吐动态预测。On the basis of model for prediction of conventional heavy oil reservoir performance by steam stimulation process,adopting energy balance theory,this paper presents a model for prediction of fractured heavy oil reservoir performance by steam stimulation process,providing analytical solutions under thermal expansion,segregation drive and capillary imbibition processes.During the solutions,effects of temperature on viscosity,oil saturation and oil-water relative permeability are taken consideration.The results between case estimation and numerical simulation using this model are similar,showing that the model can be applied for prediction of fractured heavy oil reservoir performance by steam stimulation process.
