【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。
[Abstract]:In order to determine the reasonable development mode of P buried hill reservoir, based on the analysis of percolation theory, a mathematical model of percolation in buried hill fractured heavy oil reservoir is established. According to the similarity analysis method in the equation analysis, the mathematical model of seepage flow is derived, and the 20 similar numbers needed for the indoor scale simulation are obtained. Based on the analysis of similarity number, the experimental design method is presented for the difficulty of indoor simulation. A large scale physical model was established by using similarity criterion and physical simulation method. The similar quasi array can meet the need of laboratory scale simulation experiment, and lay a theoretical foundation for the research of hot water injection development mechanism of fractured heavy oil reservoir. The results of physical simulation experiment can be used as a reference for the design of development scheme. It is useful for the study of percolation mechanism and development mode of this kind of reservoir.
