摘　　要：计算不收敛是油藏数值模拟中经常碰到的问题,而识别不收敛的原因并给以解决,能极大地提高油藏数值模拟的质量和效率。本文在静态地质模型、网格设计、流体PVT数据、岩石相渗曲线、井轨迹等方面,对计算不收敛的可能原因进行了分析,并提供了相应的解决方法。The non-convergence is a common problem in reservoir numerical simulation. Identifying the causes and solving the corresponding problems can greatly enhance the efficiency of reservoir numerical simulation. In this study, the causes for non-convergence are given in details, such as grid design, liquid PVT data, steep relative permeability curve, well trace, and static geological model etc. The corresponding solutions are put forward on the basis of these analyses.
