摘　　要：介绍了二维PEBI 网格的有关概念,对其限定条件和已有的生成方法进行了系统的分析和研究,给出了限定条件的有关规则,设计了一种简捷有效、具有较好健壮性的生成PEBI 网格的构造性算法,最后给出算法实例。笔者研究成果可以直接应用于油藏数值模拟计算。The concept of PEBI (perpendicular bisection) grid was described in this paper, then its constraint conditions as well as current generation techniques were systematically analyzed and studied. Afterwards, the related formal descriptions of constraint conditions were given. A constructive algorithm called Control Circle Algorithm was presented in this work to generate PEBI grids, which was much more effective, applicable and robust. Finally its application example was given. The research result of this paper could be directly applied to the reservoir simulation.
