| 摘 要： | 提出一种基于前沿推进的改进型PEBI网格生成方法,将其应用于油藏渗流模拟中,编制相应的油藏数值模拟器.与商业数模软件CMG的计算结果对比,验证了方法的准确性.以某不规则油藏模型为例开展数值模拟研究.结果表明,与常规笛卡尔网格相比,PEBI网格能减弱网格取向的影响.本文提出的PEBI网格生成方法在复杂油藏边界的精确描述、井位及断层内部约束条件的植入等方面具有较强的可应用性.

| Abstract: | A modified PEBI grid generation method with frontal approach is proposed,which is used to investigate reservoir modeling.Validity of the PEBI grid generation method is shown by comparing results of a self-developed reservoir simulator with that of a software CMG.A synthetic case with irregular boundary is investigated.It shows that PEBI grids reduce influence of grid orientation compared with conventional Cartesian grids.It is favorable to describe complex reservoir boundaries accurately and to implant internal constraints such as vertical well,fault in PEBI grid generation method. |
