在剖析高含水期开发过程中所表现出来的渗流现状和规律的基础上，以解决该开发阶段油藏工程问题为目的，比较系统地提出了油藏精细模拟的原理、思路和方法，提高了模拟的精度，拓宽了油藏模拟的应用领域，已经在ZW油田高含水开发单元剩余油研究和综合调整实际应用中发挥着重要作用，取得了较满意的应用效果。 Based on the analysis of the current situation and regularity of seepage during the development of high water cut stage, the principle, train of thought and method of fine reservoir simulation are systematically put forward for the purpose of solving reservoir engineering problems in the development stage, The accuracy of the simulation broadens the field of application of reservoir simulation and has played an important role in the practical application of the remaining oil research and comprehensive adjustment of the high water cut development unit of the ZW oilfield. The satisfactory application effect has been achieved.
