摘　　要：为确定P潜山油藏的合理开发方式,基于渗流理论分析,建立了潜山裂缝稠油油藏渗流数学模型。根据方程分析法中的相似分析法,推导渗流数学模型得出室内比例模拟所需20个相似准数。基于相似准数分析,针对室内模拟难点,给出了实验设计方法。采用相似准则和物理模拟方法,建立了大尺度物理模型,并进行了开发方式优选实验研究。给出的相似准数组可满足室内比例模拟实验需求,为裂缝稠油油藏注热水开发机理研究奠定了理论基础,物理模拟实验结果可作为开发方案设计参考依据,并对该类油藏渗流机理与开发方式研究具有一定借鉴意义。For confirming reasonable development mode of P buried hill reservoir,based on analysis of filtration theory,the filtration mathematical model of fractured heavy oil reservoirs in buried hill was established. According to the similitude analysis method in equation analysis method,20 similarity criteria that are required in laboratory scale modeling by deriving the filtration mathematical model. Based on analysis of the similarity criteria,aiming at the difficulties in laboratory modeling,the experiment design method was advanced. Similarity criteria and physical modeling method were applied to establish large-scale physical model,and the optimization experiment of development modes was also studied. The given similarity criterion set can meet the requirement of laboratory scale modeling experiment. It lays theoretical foundation for studying the development mechanism by injecting hot water in fractured heavy oil reservoirs. The physical modeling result can act as reference in designing development plan,and has certain referring meanings for studying filtration mechanism and development mode of such oil reservoirs.
